Warlock Right for Raiding

Warlock] PVE Raiding Compendium

If you are only interested in what a particular talent build or piece of loot does for you, I recommend using the spreadsheet by Leulier, linked at the bottom.

Talent choices

Warlocks have many great talents, and there is lots of room for customizing your spec. Consequently there are many viable hybrid builds, each requiring a different play style. To keep this guide short, I'll focus on the three main tiers and their most sensible pve raid builds. Even within those there are a lot of variations possible.


Affliction

Affliction focuses on dots. Typical demon choice for this style is imp. Even though your crit chance is lower than that of destruction warlocks, you'll want to have improved shadow bolt.

Examples
classic Spec
Raid support with UA
Raid support with Ruin

As mentioned before, there is plenty of flexibility in the early parts of the Affliction tree.

Play style
- Optimal strategy is to keep Unstable Affliction, Corruption, Siphon Life and a curse active on your target. When all your dots are up you will be using that time to throw Shadow Bolts or Dark Pact/Life tap. Good timing is important: never refresh a dot effect before it has run its full duration, but minimize the time between the last tic and reapplying. For example, you want to start casting Unstable Affliction before the last tic hits, so that the last tic happens during the cast and UA is reapplied almost immediately after.
- You probably want to use an addon like DoTimer | World of Warcraft @ Curse.com or Forte Gaming / Forte Warlock Addon for this. There is no fixed rotation since your dots have different durations.
- Get your imp buffed, blessing of wisdom helps a lot for his mana regeneration, which you can siphon off with dark pact. Imps can only be buffed when they are not phase shifted.
- Despite Drain Life getting a lot of benefits, Shadow Bolts will always outdamage it. Drain life is the most mana efficient spell since you're effectively gaining life/mana.

Strong and weak points
- More mana efficient and self sufficient than other trees.
- Ideal in situations when two or more mobs are being tanked, as you can dot them all.
- This spec provides less burst damage, and scales worse with gear than other specs.
- Bloodpact can be nice to boost party hit points, especially on fights where a tank can get flattened fast, or where there is lots of aoe damage on the raid.
- Can come with Malediction, which scales with the amount of Shadow/Arcane users in the raid. It adds 2.7% over the untalented CoS. (113% talented, 110% untalented, 1.13/1.1 = 102.73%)
- Can come with Shadow Embrace, which reduces the melee damage on the tank by 5%. This effect is multiplicative: if your tank would take a 1000 hit it'll be 950 with SE.
- Due to the high amount of raid benefits (Blood Pact, Malediction, Shadow Embrace), having at least one affliction warlock in a raid is recommended.
- This build uses a lot of debuff slots. As soon as the cap of 40 debuffs on a mob is reached, the oldest ones will start falling off. For this reason, too many affliction warlocks in a raid will hamper one another. If you're having trouble with debuffs being pushed off, you can use a lower rank of CoS (see Curses, below), have all warlocks use only the optimal dots, or get Warlocks to respec to another tree. (also, see the Debuff count addon linked at the bottom of this post)
- Most affliction warlocks use Suppresion to reach the hit cap early on, and spec out of it when they obtain more +hit on their gear.

Variants
Affliction builds have access to several talents that can support the raid: Improved blood pact, Malediction, and Shadow Embrace. Most variants are therefore tradeoffs between these and talents that will increase the Warlock's personal dps.

Optimally just one warlock in the raid should have them. The UA support build is recommended at starting levels, with the Ruin support build likely to perform a bit better at end level raiding, due to high amounts of hit and crit rating on pieces at that level.

30/21/10 keeps popping up as an alternative build. It's been harshly criticised every time it was proposed. See post #78 and beyond in this thread for details.


Basic gear choices (see below)
Spell hit (until capped with suppression) > Spell damage > Spell haste & Crit

After obtaining 76 hit rating with 5/5 Suppression, warlock dots are hit capped. Further extra hit rating only affects Shadow Bolts/Immolate, and is worth less than spell damage on a point-for-point basis.

Demonology

Demonology in raids is about making best use of your top tier Demonology talents. The strength of these can make up for the lackluster mid tier Demonology ones.

Demonologists get a boost to spell power, get a 5% damage bonus due to soul link, and get +5% to crit with spells. It is vital their pet stays alive, though. A Demonologist without a pet is very ineffective.

Raiding With Felguard (SSC, TK, Hyjal, BT) - The Warlocks Den is a great resource for aspiring Demonologists.

Examples
Standard Spec with high focus on ISB
Another version with improved Life Tap
Demonology without a Felguard using a Succubus instead to obtain Ruin.

Play Style & tips
- Keeping your Felguard or Succubus alive is key. Micro managing your pet is vital, since it dying means losing a lot of dps.
- Spell rotations are similar to affliction, with a higher accent on (improved) Shadow Bolts.
- Remember to have your pet attack from the back. Melee attacks from the front can be parried, which can cause a faster attack on the MT. Avoid this at all costs. Update: this has been patched, and demons will now position themselves behind their target.
- Ask for buffs on your pet. His stamina and intellect will boost your attack power, and it'll allow him to stay alive longer. BoW should help too
- One point in Mana Feed will allow the Felguard to cleave for 5 minutes
- If you choose to use a Succubus, don't have her use Lash of Pain on the primary target, as it eats ISB debuff charges.
- [Sporeling Snack] and [Kibler's Bits] work on Warlock Pets. The latter is a reward from the cooking quests from the goblin in Shattrath.
- Greater blessings cast on warlocks will also affect their demons, except the Felguard. Felguard and hunter pets get the greater blessings cast on Warriors instead. Phase shifted imps do NOT receive buffs.
- Demons about to die can be dismissed and nearly instantly resummoned with Fel Domination. This will conserve their buffs, and bring them back with full health and mana. The command to dismiss a demon is /run PetAbandon(), which can be macro'd and assigned to a button.

Strong and weak points
- Demonology relies on having the Felguard/Succubus out, so the effectiveness varies a lot. Some fights are brutal towards pets.
- It is the most versatile spec due to the demons each having different effects on you.
- Best choice for Warlock offtanks in specific encounters (Leotheras being a prime example)
- Demonology is probably the least gear dependent of all three specs. Exception is the tier 5 two piece set bonus : [Hood of the Corruptor]. This set bonus make a vast difference. [Void Star Talisman] is also really useful in keeping your pet alive. Before obtaining those items, demonology is likely to perform less well than the alternatives due to the extra healing required on the pet. Shadow Priests in your group will obviously help a lot for pet survivability.
- Demonologists want a raidbuffed demon out at all times. Make sure to resummon it before raid buffs are applied, or you'll end up having to ask for buffs on your pet. These buffs have huge effects on your demon and on your spellpower. It can become quite a hassle to have to ask for buffs: most healers don't have pets included in their UI and having to ask for buffs on a pet can become quite tedious. Especially the Succubus is prone to dying quite fast.

Variants
The Succubus build is an alternative to 0/21/40. It has Demonic Tactis (5% crit) and Soul Link and Demonic Knowledge (typically around +200 damage for a raid buffed succubus). It doesn't have the 0/21/40 Backlash (3% crit) and SnD (20% spellpower to Shadow Bolt/Incinerate). For reference, a Succubus has a lot less hit points and has no avoidance to aoe effects compared to a Felguard.

Basic gear choices (see below)
Spell hit > Spell damage > Spell Haste > Spell Crit

As mentioned before, tier 5 two part bonus is very useful for this spec, as is [Void Star Talisman] which drops from Solarian in TK.

Stamina and Intellect and Demonic Knowledge:
Demons get a Stamina boost equal to 30% of their owner, same for Intellect, which translates into 15% Spell power.

With talents:
1 stamina on items =
1.15 stamina on Warlock (Demonic Embrace) =
0.3968 Stamina on Demon (Fel Stamina 15%, Demon Sta contribution 30%) =
0.0595 spellpower (15% Demonic Knowledge)
0.0720 spellpower with kings on both demon and owner

So 1 sta = 0.072 spellpower with BoK.

It also boosts your Succubus hit points with 2.9 without kings (update needed for Felguard, can anyone tell me the stamina to hit point conversion? It's demon dependent, Succubi get 7 health per sta)

1 intellect =
0.345 int to demon (Fel Intellect 15%, Demon Int Contribution 30%) =
0.052 spell power (15% Demonic Knowledge)
0.062 spell power with kings on both demon and owner.
So with Kings 1 int = 0.062 spellpower (and 0.3 crit rating, as listed further in this post)

Gearing for Stamina or Intellect in order to obtain higher spellpower through Demonic Knowledge will yield very insignificant returns, especially compared to how buffs like Fortitude and Arcane Intellect on the demon will affect it. Because of this, Stamina's only real function is to give you (and to a lesser extent, your demon) a larger health pool.

Destruction

Due to Shadowfury's limited use in raids, the typical Destruction build is 0/21/40, taking a few subpar talents in Demonology to obtain Demonic Sacrifice, which boosts shadow or fire damage by 15%.

This build focuses primarily on Shadow and Flame, Ruin, and Demonic Sacrifice, resulting in Shadow Bolts with a high damage coefficient from spell power. (3/3.5 + 0.2 from talents, or rougly 105.7%).

It's very important to keep the Improved Shadow Bolt Debuff (ISB) up as much as possible, since it provides 20% extra shadow damage to the entire raid while it is active. (including dots - this is a common misconception). Destruction warlocks consequently put a higher value on crit rating than other builds do, since it helps with ISB uptime..

Updated for 2.4:
Since 2.4 Emberstorm was buffed, making Fire destro a valid alternative that uses Incinerates instead. It is currently being debated which is better.

This spec scales best with gear, and will clearly outperform affliction on high gear levels (Hyjal/BT). For starting raiders, affliction gets a head start due to the hit bonus of Suppression and the mechanics of dots putting spell damage to work while needing virtually no other stats. When +hit gear becomes more easily available, the gap closes.

There has been much debate about what the exact gear treshold is, for destruction to outperform affliction. Opinions are divided on the matter. Both specs require different play styles, resulting in boss fights typically favoring one spec over the other. ISB damage is hard to measure. Because of this it is virtually impossible to get solid evidence. The debate is unlikely to cease any time soon.

The old rule of thumb "you need Hyjal/BT gear for destruction to be viable" is most definitely untrue. Anecdotal evidence suggests Destruction warlocks with Kharazan or tailored gear outperform equally geared affliction warlocks. Your mileage may vary, as player skill and latency are likely to be far more determining factors.


Examples
Default build
Hybrid Fire Destruction
Full fire destruction
Destruction with Siphon Life
Destruction with Shadowfury

Play style
- Spam Shadow Bolts and curses. Life Tap at opportunate times. Bring potions, healthstones and bandages. Fire destro will use Incinerates instead, and needs to make sure Immolate is up.
- Curse of Doom and Curse of Agony still provide higher dps over regular spells provided your target lives long enough.
- At lower spelldamage levels Corruption will be viable, provided you have enough debuff slots, you get the full 6 tics, you're not threat capped and you don't need to move to cast it (no extra range talent).
- for Shadow destro: if CoE and improved Scorch are up, talented Immolate will outdamage Shadow Bolt on damage-per-casting-time at every realistic gear choice, even if accounting for the extra mana cost and ISB procs. If all of these factors are absent, Shadow Bolt might be the better choice depending on gear (better gear favors SB).
- At the start of a fight you may want to apply a curse, Corruption then Immolate regardless of gear, since starting early with Shadow Bolts can easily outaggro the tank if he gets an unlucky string of dodges/misses/parries on the pull, and you crit your first couple of spells.
- Since you require Life Taps, having some way to monitor raid health is recommended. When the raid is topped up, a Life Tap or two will result in Flashes of Light or Renew/Rejuvenation on you, all of which are very mana efficient. Moderation is key, since a string of consecutive Life Taps will set off alarm bells, diverting healer attention.
- Summoning an infernal will not remove your Demonic Sacrifice, and is a nice way of increasing dps. It does around 30-40k damage in the 5 minutes before it breaks the enslave. It's usable in Sunwell (notably on Brutallus) and in Mount Hyjal. It is not usable on Archimonde or Kalecgos, as being out of range of your infernal can set it off on the raid. Changed in v2.4.3 - Infernals are level 50 now.

Strong and weak points
- This spec has the most powerful burst damage. This is a boon when things need to die quick, but it makes it harder to manage threat while still maximizing dps.
- It is the least mana efficient spec, requiring the occasional heal to be able to keep dpsing.
- Destruction warlocks will need a healthy amount of healthstones, healing potions and bandages in case healing is scarce. Having to stop dpsing to bandage or drain life will make your dps drop dramatically.
- Scales the best with gear, due to Shadow Bolts getting a 106% bonus per +damage (3/3.5 + 0.2 from talents), which result in more dps bonus than any other spell for any spec.
- ISB uptime is hard to measure or model, but provides a boost in shadow damage to the entire raid.
- This spec requires a lot less management since there are no real dots to keep track of, and no pet that can die. Some warlock dislike the lack of variety in spells used, others prefer it because it allows them to focus on other things, like keeping an overview of what is happening.
- Conflagrate, like Shadowburn has very limited use in raids, as Shadow Bolts outdamage it.
