Hi and welcome to the Method Warrior Guide for Dragon Soul !

I am Berzerkvladî (http://eu.battle.net/wow/en/character/xavius/Berzerkvlad%C3%AE/simple) and would like to give you a brief overview about Dragon Soul 25man Heroic Raiding (http://www.wowwiki.com/Dragon_Soul) regarding Protection (http://www.wowhead.com/talent#LG0cZ0bZIcGzRRodbu), Fury (http://www.wowhead.com/talent#LG0cZsrbcskkMfdZb) and Arms (http://www.wowhead.com/talent#LGRccRMRurzcrZh).

Allthough warrior isnīt superior to other classes dps- or tank-wise your great mobility and raid-wide utility is going to make you a viable choice in for every encounter.

In this guide Iīll focus on the optimal spec and talents, when to use defensive and offensive cooldowns, which items are essential for certain fights and also give you some tips and tricks you maybe didnīt know yet.

Be aware that this is a guide for advanced players and will not provide any basic infos about the encounters.

To provide a better overview ill seperate this guide into 2 sections:

Protection
Fury and Arms


Letīs take a closeer look at the bosses:



Morchok

<div style='float:left;margin-right:15px;'>http://i.imgur.com/OYbBw.jpg</div>Protection

You want to use your Shieldwall with 4-set (http://www.wowhead.com/spell=105911) to cover both a Stomp (http://www.wowhead.com/spell=109034) and Crystal (http://www.wowhead.com/spell=108572). You want to make sure you use it in a timely manner that will allow it to be back up when the boss gains Furious (http://www.wowhead.com/spell=103846). Use your Rallying Cry (http://www.wowhead.com/spell=97462) when you feel it is needed, pay attention to your raid frames - do people need a RC to survive the stomp?
Drag the Boss close enough to Resonating Crystals, but stop moving few seconds before he Stomps to give your raid and the second Stomp soaker enough time to position and move closer after the Stomp.

Fury and Arms

On this fight Fury is slightly better than Arms due to its huge burst dps during execute phase while Morchock becomes Furious.
The AOE (http://www.wowhead.com/spell=103785) phase lasts 15 seconds. You canīt stay in all the time. There are two different ways to handle this.
The first option is to stay in when the AOE phase beginns and dps 6-7 sec then Heroic Leap (http://www.wowhead.com/spell=6544) out. As soon as your debuffs resets Charge (http://www.wowhead.com/spell=100) back in and after soaking another 3-4 stacks the phase will end. This is what Arms should do. The main benefit is that your Slaughter (http://www.wowhead.com/spell=84586) and Rend (http://www.wowhead.com/spell=772) dont expire and additionally you trigger Juggernaut (http://www.wowhead.com/spell=64976).
The far better option for Fury is to dps only ~ 2-3 sec and Intervene (http://www.wowhead.com/spell=3411) out. Make sure someone is close enough so you can Intervene him. As soon as your debuff resets use your Shout and Leap on the boss.

Watch the Black Phase timer and donīt use Colossus Smash (http://www.wowhead.com/spell=86346) shortly before.
Make sure your dps cooldowns are ready during the execute phase and use Shieldwall and Rallying Cry to assist your healers to mitigate Stomps.
Warriors usually have no trouble surviving the Stomps due to their high armor and Healthpool compared to other dps, but taking less damage relieves the healers.
Equip your Shield on Stomps while Morchock is Furious.



Warlord Zon'ozz

<div style='float:right;margin-left:15px;'>http://i.imgur.com/5EVVR.jpg</div>Protection

You should have some defensive cooldowns up for each Psychic Drain (http://www.wowhead.com/spell=104608), for example; Shieldblock > Mirror of Broken Images (http://www.wowhead.com/item=68713) > Shieldblock. This will mitigate spike damage and reduce the amount by which the boss heals.
Shieldwall (4 set) is used during the 1st and 3rd Black Blood phase (or a similiar assignment), put it up at the start where Tentacle stacks (http://www.wowhead.com/spell=110322) are at maximum and hence raid damage taken is at highest point. Rallying Cry is also used during the Black Blood phase when you feel it is required.
You want to make use of a Priest/Paladin cooldown on yourself at high Focused Anger (http://www.wowhead.com/spell=109410) stacks, ideally the last 10-15 seconds before the boss will soak an orb (again when incoming damage is at it's highest). This should be up every Phase 1.
You need to pay close attention to the Physic drain timer, you don't want to turn the boss on the raid when it is about to land - particularly when you are trying to pick up the Void (http://www.wowhead.com/npc=58473) to enter Phase 2.
Claws of Go'rath (http://www.wowhead.com/npc=55418) spawn on two different locations, one should be tanked by a dps DK/Feral/Warrior. Move to the other Claw and the boss will come to you after a set period.

Fury and Arms

Due to Zon'ozz becoming Diffused (http://www.wowhead.com/spell=106836) and taking more damage the longer the fight lasts Fury is the best dps spec you can go for.
Even though Enraged Regeneration (http://www.wowhead.com/spell=55694) is a huge dps loss you might have to use it during the Black blood phase, the heal with decent mastery is insane, however you should use Shieldwall first since its less dps loss.
Donīt ever use Recklesness (http://www.wowhead.com/spell=1719) during the Black blood phase, itīs unnecessary damage taken. You will most likely be assigned to dps the Claw of Go'rath next to the boss.
Fury should focus the Claw and put Cleave as higest priority during the first black phase. During the second black phase when Zon'ozz has a higher amount of Diffused stacks focus Zon'ozz and Cleave the claw. On the third black phase ignore the claw and dps only the boss. In case you play Arms use Sweeping Strikes and stay fulltime on him.
Use your cooldowns combined with Executioner (http://www.wowhead.com/spell=20503) and potion after the last Black Phase, this will enable highest overall dps.



Yor'sahj the Unsleeping

<div style='float:left;margin-right:15px;'>http://i.imgur.com/45kzr.jpg</div>Protection

Once again for Prot warriors Safeguard (http://www.wowhead.com/spell=46949) is an excellent choise. After switching tanks use it to give the other tank 30% dmg reduction and prevent the boss from switching back due to high Vengeance and threat.
Dont waste your personal cooldowns for anything else than the combination of yellow (http://www.wowhead.com/npc=57387) and purple (http://www.wowhead.com/npc=57388). Enraged Regeneration doesnīt give Deep Corruption (http://www.wowhead.com/spell=108220) stacks and Shield Block reduces magic damage taken by 20%.

When Globules spawn donīt dps the boss, switch and help on the Globules, apply Sunder Armor, but make sure to be in range of your healers, you still have Void Bolt (http://www.wowhead.com/spell=109551) doing alot of damage on you.If itīs on the other tank use Safeguard on him.
An optional tip I can give you is to use Impending Victory (http://www.wowhead.com/spell=80129) and Glyph of Victory Rush. This gives your Devastate a 50% chance to enable Victory Rush, but it heals "only" for 15% of your total HP and doesnīt increase Deep Corruption Stacks. As soon as you have Globules, Forgotten Ones or the Boss below 20% just spamm Devastate till it procs and use Victory Rush.

Fury and Arms

Even though Arms seem to have much higher dps on this fight its meaningless. Arms can push their overall dps by AOEing Forgotten Ones (http://www.wowhead.com/npc=56265). This increases your overall dps but is a huge dps loss on the boss. The only reason to play Arms here is lack of 4% physical dmg or 30% bleed dmg debuff.
Fury has decent mobility, use Heroic Leap when Globules spawn to get as close as possible, you wonīt be in melee range yet, Intercept them and use Heroic Fury to reset the Intercept. You will need to Intercept either the Boss or the Mana Void after killing the Globule. Donīt use Whirlwind to AOE on this fight, its a dps loss on the boss, just Cleave and Heroic Leap. An excellent item choise for this fight is Bone-Link Fetish (http://www.wowhead.com/item=78002).

Due to your higher HP pool as Fury and passive healing with Bloodthirst you should always try to soak Searing Blood (http://www.wowhead.com/spell=108357) ticks which occur while the Red Globule buff is active. Especially when Purple is active try to soak as many Searing Blood ticks as possible and negate the dmg with Shieldwall as soon as you reach a high amount of Deep Corruption stacks and then use Enraged Regeneration.



Hagara the Stormbinder

<div style='float:right;margin-left:15px;'>http://i.imgur.com/oMTWu.jpg</div>Protection

Not much to say about this fight.
Use your personal and Priest/Paladin cooldowns on each Focused Assault (http://www.wowhead.com/spell=110898)and make use of Rallying Cry and Raid-Shieldwall during Frost or Lightning phase. Try not to break line of sight when tombs spawn, but keep the boss close enough to allow dps to AOE.

Fury and Arms

Time your offensive cooldowns and assign Shattering Throws (http://www.wowhead.com/spell=64382) for each stun phase.
Depending on what you are supposed to do both specs have benefits - Arms is insane for killing Tombs and Fury dmg is astonishing during the stun phase. Weakness on Hagara lasts 15 sec. Make sure your Heroic Leap is off the cd when Frost or Lightning phase ends so you can Leap on the Boss. This means that you always use Charge or Intercept to get close to the Elemental (http://www.wowhead.com/npc=56700)or Binding Crystal (http://www.wowhead.com/npc=56136).
While chaining Lightning Conduit you should use your defensive cooldowns.



Ultraxion

<div style='float:left;margin-right:15px;'>http://i.imgur.com/xhLDp.jpg</div>Protection

This is a pure dps and heal fight.
Due to Thralls buff Last Defender of Azeroth (http://www.wowhead.com/spell=106218) tanking is relatively easy. You can use your Defensive CD's at the start before Thrall buffs you - Defender of Azeroth is refreshing the CD.[/COLOR] This buff reduces defensive cooldowns by 50% and increases their duration by 100% - this enables 100% uptime of Shieldblock.
The only things you have to be aware of are Fading Light (http://www.wowhead.com/spell=110078) and Hour of Twillight (http://www.wowhead.com/spell=109417). Press Heroic Will (http://www.wowhead.com/spell=106175) in the very last second to maximize your dps uptime. Depending on Coooldown assignments you may want to use the Shieldwall Glyph (http://www.wowhead.com/item=45797) which combined with the 4-piece provides 10% less damage taken for the whole raid (20% for you). Safeguard is once again a must have ability to improve survivability of weak soakers for HoT and Impending Victory grants you some healing during the execute phase.

Fury and Arms

On this fight Fury and Arms dps are pretty equal. Fury is slightly better due to its higher survivability - stronger Enraged Regenetarion and Bloodthirst healing. If you are forced to use Shieldwall or Enraged Regeneration to survive Arms loses less dps than Fury does. However, the differences are so small that it doesnīt really matter and you should just play the spec your gear fits better with.
To optimize your dps donīt use Heroic Will to early and delay your last Death Wish (http://www.wowhead.com/spell=12292)/Deadly Calm (http://www.wowhead.com/spell=85730) and second Recklesness and Potion (http://www.wowhead.com/item=58146) until you have Executioner stacked up and Enrage proced.



Warmaster Blackhorn

<div style='float:right;margin-left:15px;'>http://i.imgur.com/jBVV4.jpg</div>Protection

Position both Twilight Elites in phase 1 close to the Drakes so they can get cleaved and donīt stay in front of the Dreadblade (http://www.wowhead.com/npc=56854) if you are not supposed to tank it.
For this fight you should use Glyph of Sunder Armor (http://www.wowhead.com/item=43427). Donīt Charge or Intercept the Sapper, if you have DKs let them grip, else you can leap, use Concussion Blow (http://www.wowhead.com/spell=12809) or stun at range with Shockwave. Use your Shieldwall and Rallying Cry in a rotation with other Cooldowns to cover the 5 Twilight Onslaught (http://www.wowhead.com/spell=107588)s (typically we will do; Aura Mastery -> Divine Guardian -> Shield Wall -> Aura Mastery + Rallying Cry -> Disc Barrier).
During the second phase donīt move the boss around to much, else things get messy. Use your Shieldblock for Devastate (http://www.wowhead.com/spell=108042) after or shortly before a Roar (http://www.wowhead.com/spell=109229) occurs. Use your Shieldwall and Rallying Cry for the first couple of Disrupting Shouts so you have them up again for the last (again use a CD rotation, we stick to the same assignment as that used for Twilight Onslaught - see above). You can use your Safeguard on the other tank for Devastate, but use it early enough so you soak an ordinary hit and not Devastate - or the other tank should make use of a cancelaura macro (/cancelaura intervene) as Safeguard is a seperate buff from the actual intervene buff itself.

Fury and Arms

Arms is much stronger in phase 1 due to the better AOE on the Elites with SS, BS and Rend/Blood and Thunder. However fury burst is much stronger in phase 2 and since dps on the Elites should be no issue you should play Fury.
Blade Rush is probably the most fatal Ability you have to handle on this fight. Donīt stay between them and the ranged dps or healers or in front of them. Just try to stay somewhere on their side and you should be able to avoid a large amount of Blade Rushes.
Use your dps Cooldowns on Gariona and donīt cleave on Blackhorn. Itīs important to get rid of her as fast as possible and keep Blackhornīs HP high enough until she flies away so he does less damage on Disrupting Roar (http://www.wowhead.com/spell=109230).



Spine of Deathwing

<div style='float:left;margin-right:15px;'>http://i.imgur.com/pEBFE.jpg</div>Protection

This is one of the trickier fights for tanks. You have to keep an eye on the Fiery Grip (http://www.wowhead.com/spell=109457) timer. Coordinate your taunt with Fiery Grip (http://www.wowhead.com/spell=109459) breaks. Always try to taunt through the trail of Residue (http://www.wowhead.com/spell=105223) while standing on the other side of it so you donīt get hit while the Amalgamation moves and gains stacks. Use the Blood and Thunder (http://www.wowhead.com/spell=84615) and Thunderstruck Talents while gathering Bloods and make use of the Shockwave (http://www.wowhead.com/item=45792), Thunderclap (http://www.wowhead.com/item=43399) and Demoralizing Shout (http://www.wowhead.com/item=43398) Glyphs. Make sure Demo Shout and Thunderclap are up all the time, this will reduce your damage taken and will, combined with Leap and Intervene to kite the Bloods, make you survive much longer on the third Armor Plate.
Use your Raid-Cooldowns either for the Explosions or the Barrel Roll. Keep Enraged Regeneration for Searing Plasma on the third Plate.

The probably most important thing here is a good UI. You can use Nameplate Addons to make targeting bloods easier, or use mouseover macros so you donīt even have to target them. Sometimes your Thunderclap or Shockwave is on cooldown and you have to use other abilities, else the Blood runs to another target when taunt ends. The following macro is just one of those we used, you can use this for Devastate or any other ability to build threat on a taunted Blood without switching target.

#showtooltip Taunt
/cast [target=mouseover,harm,nodead]Taunt
/cast Taunt
/startattack

We are using Tidy Plates Threat Plates - here is some quick introduction how to config it for Spine:

Open Config (/tptp) -> Custom Nameplates
Corrupted Blood
Custom Scale - 65% (any value between 50%-75% is okay, shouldnīt be to small)

Obviously this will put Corrupted Blood's nameplates at 65% of the size of your normal nameplate (on this fight the tendons and Amalgamation). This way it is easy to differentiate between the Bloods so you dont taunt the wrong targets and still can track the HP of the Amalgamation.

In case you are not the one tanking and kiting the Bloods and supposed to taunt Bloods with lower HP to the spine to get some Residue for the Amalgamation you should enable the following option for Spine ( disable it afterwards, itīs not usefull on other fights )

This will change the Color of the Nameplate depending on how much HP they have and ease taunting.

Open Config -> Healthbar
Scroll down and enable: "Color HP by amount"

Sco was drawing a nice self-explanatory picture for you to explain the kiting path more detailed.
<div>http://img806.imageshack.us/img806/9682/spinekitepath1.jpg</div>
Donīt forget to use Demoralizing Shout and Thunder Clap when things get messy, you will get hit by Bloods there is no escape, you just have to reduce the amount and force of their hits as much as possible.
Obviously you can optimise this in some cases for example if Tentacles are left or right of 4. and/or 5. you can charge them, or as Worgen by using Darkflight, Rocket Jump or having additional Grips to use after 3.

Fury and Arms

This fight is all about burst dps over a small time-span. Allthough Arms overall dps is higher on this fight this dps is irrelevant. All that counts here is the Tendons and Amalgamations damage.
There are two different builds for this fight:
I. For maximum Tendon damage a mastery heavy Fury build with very low expertise, softhitcap and a proc trinket like Creche of the Final Dragon (http://www.wowhead.com/item=77992) combined with an on use trinket like Rotting Skull (http://www.wowhead.com/item=77116) or Apparatus of Khaz'goroth (http://www.wowhead.com/item=69113) is the best way to go.
II. Depending on your raid setup you might have to do alot dmg on the Amalgamation, in this case the only thing you change is that you get expertise caped, but remain mastery > hit unless you drop below ~ 12% hit.

The perfect start for Tendon dps is to pre-stack your Executioner on either the dying Amalgamation or on Blood. Donīt get hit by the Nuclear Blast.
Track your Trinket Proc and Enrage. You can pre-use Deathwish since it lasts 30 sec and you want to maximize the use of Recklesness, Trinket, Potion and Colossus Smash.
If you are lucky enrage procs early, then you just use everything. In case it doesnīt use after 3-4 sec Rotting Skull, and after another 2-3 sec Recklesness so they last till the tendon despawns. Keep Colossus Smash for the very last 6-7 sec if Enrage doesnīt proc. Since Leap and Intercept are off the GCD use them to dps the Tendon. Donīt forget to use Shattering Throw

To enable fastest dps on the Tendons you can target it per macro:

/cleartarget
/clearfocus
/targetexact Burning Tendons
/focus target
/cast [target=focus] Bloodthirst



Madness of Deathwing

<div style='float:right;margin-left:15px;'>http://i.imgur.com/p76fT.jpg</div>Protection

Blood and Thunder is essential for AOE on Bloods and Safeguard is AMAZING for improving the other tanks survivability on Impale.
You should use Glyph of Cleaving (http://www.wowhead.com/item=43414) and Thunder Clap and as 3rd Glyph either Schockwave, Resonating Power or Sunder Armor (http://www.wowhead.com/item=43427). I personally prefer the last one. During the first 4 phases this wonīt be really usefull but in the final phase Sunder Armor is superb to apply the debuff on 2 Elementium Fragments (http://www.wowhead.com/npc=56724) or both Elementium Terrors (http://www.wowhead.com/npc=56710) at the same time.

All you want is high Mitigation which means Armor and Stamina. Without a certain amount of Stamina you will get oneshot on the 4th plattforms without Alexstraszas HP-Buff. The Effective Health can be increased by using Absorb-Shields on the tank right before Impale (http://www.wowhead.com/spell=109631) lands. This is why the most important item for tanks on this fight is Stay of Execution (http://www.wowhead.com/item=68996)- the Firelands reputation tank trinket. Allthough it has no Stamina the on use effect makes it superior to any other trinket ingame.

For the final phase try to avoid as much damage as possible from Elementium Terrors. Let the other tank pick the 2 Terrors up and when he has 4-5 stacks use Challenging Shout (http://www.wowhead.com/spell=1161) - this will cause both of the Terrors to switch to you for 6 seconds before auto switching back to the other tank (as this is not a permanent taunt), this is PERFECT for resetting the first tanks debuffs. When using taunt try to taunt them from one edge of the Time Zone (http://www.wowhead.com/spell=105830) to the other edge. The Terrors hit 50% slower while inside this zone. You can also easily reset the Tetanus (http://www.wowhead.com/spell=109603) debuff by using Leap or Intervene and kite them for few seconds. IMPORTANT; Vigilance will not reset your Taunt cooldown on Terrors - they only apply debuffs, not physically melee hitting.


As a side option: Let a Heal/Ret Paladin or dps Warrior/DK taunt the Terrors with Righteous Defense, Challenging Shout or Grip and Dark Command. They will run few seconds towards the player taunting them, meanwhile the debuff on the tanks resets, and if the player is far enough they will turn back without even hitting that player.

When your raid starts AOEing the Bloods or Fragments make sure the Terrors are close enough. They will take insane damage caused by Spellweave (http://www.wowhead.com/spell=109611) procs which will end up giving you additional time to dps Deathwing.

Fury and Arms

On this fight once again you should play Arms or Fury depending on what your raid needs most - AOE Burst on Bloods, Fragments and Terrors or sustained and very high damage on Corruptions, Tentacles Parasites and Deathwing himself.
No matter which spec you play, warrior is most likely the only melee that is supposed to switch on Elementium Bolts and Parasites that spawned inside the Time Zone. Our mobility is a gift and a curse at the same time.

Arms, supposed to do insane AOE damage should go for hit-softcap and mastery and drop expertise as low as possible. The Stat priority is Hitcap>Mastery>Crit>Expertise>Haste. Why Mastery > Crit? Mastery increases the chance to proc Strikes of Opportunity (http://www.wowhead.com/spell=76838) and SoO can trigger Spellweave.
On the first 3 plattforms use your offensive cooldowns on the Curruptions, on the 4th use it for the first Parasite spawn and in the final phase use them after the second wave of Bloods spawned.
Keep your Sweeping Strikes and Bladestorm for every single Parasite, spread Rend with Blood and Thunder before you start AOEing.

Fury is supposed to do as much damage on the Corruptions as possible, stay expertise caped and crit>hit>mastery.
You can either focus the Parasite with Single target abilities and only Whirlwind/Cleave for AOE or switch to combat stance and use Thunderclap aswell. While your DPS cooldowns are up donīt stancedance and dont AOE, focus the Parasite only with single target abilities.

A trick you should use for all specs is to use abilities that are off the GCD to proc Spellweave: Intercept and Heroic Leap.
Even as Arms its more effective to use Intercept to proc Spellweave instead of Charge to proc Juggernaut. Make use of Bone-Link Fetish in both specs, due to its AOE proc it is best in slot for this fight.

You Should also use Eye of Unmaking (http://www.wowhead.com/item=77997)/Vessel of Acceleration (http://www.wowhead.com/item=69167) > Rotting Skull (http://www.wowhead.com/item=77116)/Apparatus (http://www.wowhead.com/item=69113) > Creche of the Final Dragon (http://www.wowhead.com/item=77992). The CotFD proc is to rng and the on-use trinkets are inferior due to the fact that the single target burst phases are to infrequent and there is to much time between them. Another reason is that alot of burst damage is needed for AOEing and their Effects dont affect Spellwave.

Anyway there is an exception for Arms. In case you donīt have EoU and BL-F you should use Apparatus>Vessel. You will have higher mastery than crit, which will make Apparatus give you almost 3k mastery, and this will affect the procchance of SoO which will end up in having more Spellweave procs.

Dpsing the Blistering Tentacles (http://www.wowhead.com/npc=56188) is tricky. Assign beforehand which one you are going to focus. Allthough Cleave and AOE doesnt work on the Blistering Tentacles you should still use Cleave / Sweeping Strikes during this phase while focusing the Blistering Tentacles, the Cleave/SS will hit the Arm/Wing Tentacle.
During the Final Phase always start with Leap on the Bloods, followed by Intercept and then Whirlwind -> Thunderclap for Fury or TC-> Rend -> WW -> SS+BS for Arms.

Focus the Bloods in the front with your single target abilities and try to stack your Executioner on them. This priority counts for Fragment waves aswell but try to either focus camps with several Fragments close together or Fragments that are far away - keyword "high mobility".

Hope you enjoyed reading our guide and found some usefull informations. If you have any questions or need more detailed information feel free to post in our Strategy Forum (http://www.methodwow.com/board/forumdisplay.php?6-Strategy).

Excellent! Even as other tank classes this gives incredible insight in all of the heroic encounters and really good tips on when you should and shouldent do certain ability's even when you feel the pressure is at the max.

Good job and well done!

"Our mobility is a gift and a curse at the same time." :)

Awesome guide, have a few suggestions I'd like to point out


Are you suggesting to go 31/7/3 arms for Madness of Deathwing? (Focus the Bloods in the front with your single target abilities and try to stack your Executioner on them.). I find it weird because you're going to miss a lot of spellweave from the blood and thunder (rend).
Also you forgot to mention when to use Recklessness in this fight - you'll want to use it when you've spread out the blood and thunder and when you're about to use bladestorm on the Regenerative Bloods right?
About "you should still use Cleave / Sweeping Strikes during this phase while focusing the Blistering Tentacles, the Cleave/SS will hit the Arm/Wing Tentacle." dont you think it would be better if you single-target down the blistering tentacles ASAP? SS is still fine in this case though with the glyph
About the Warmaster Blackhorn fight - Remember to charge the sapper after your DK has deathgripped it when it spawns, it will make it a lot easier for the raid to kill it.
About the Hagara fight - I hardly disagree on the part saving Heroic Leap until the phases end. It should be used to avoid getting killed by the Ice Waves in the Frost phase, when you get the debuff on you.
About the Yor'sahj fight - Remember to pop Recklessness when you're stacking up, causing the adds to spawn. This, combined with the suggested item Bone-Link Fetish, will signifanctly increase your dps. Spread the b&t first.
