Destruction 101: PvE
The Spec:
If you're going for maximum damage through talents, then this tree is the way to go.
You're going to be getting:
Destruction Tree
Bane (3/3)
Shadow and Flame (3/3)
Improved Immolate (2/2)
Emberstorm (2/2)
Improved Soul Fire (2/2)
Backdraft (3/3)
Shadowburn (1/1)
Burning Embers (2/2)
Soul Leech (2/2)
Nether Ward (1/1)
Fire and Brimstone (3/3)
Shadowfury (1/1)
Nether Protection (2/2)
Empowered Imp (2/2)
Bane of Havoc (1/1)
Chaos Bolt (1/1)
Demonology Tree
Demonic Embrace (2/3)
Dark Arts (3/3)
Mana Feed (2/2)
Affliction Tree
Improved Corruption (3/3)
Bane of Havoc:
This handy little device appears to be a must in the new raid, Dragon Soul. While the Bane is on a target, it will receive 15% of all damage done to any other targets, so for an existing example, putting BoH on Beth'Tilac as she runs away upstairs so while you kill the spiders downstairs, she's receiving 15% of all that damage.
Be warned however that you can only put one bane on one target at a time, so don't forget to swap it for Agony or Doom when you're switching into that target.
Glyphs:
Prime Glyphs:
Glyph of Imp
Glyph of Immolate
Glyph of Conflagrate
Major Glyphs:
Glyph of Soul Link
Glyph of Life Tap
Glyph of Shadowflame - This Glyph spot is personal choice, I tend to stick with Shadowflame as a 70% slow can be very useful in some situations.
Minor Glyphs
XXX
XXX
XXX
All Minor Glyphs are personal choice, as they provide no damage/survival benefit.
The Rotation:
Destro is a lot like Subtlety PvE in the sense that it requires one certain buff to have 100% uptime (if possible), this buff is provided by Improved Soul Fire, and when active increases all Fire and Shadow damage done by 8% for 15 seconds after dealing damage with Soul Fire, this is going to be upped to 20 seconds in 4.3. Always apply DoTs when this buff is active, as it's a great boost and should never be forgotten.
So without further mention, the rotation (although it is more of a priority queue):
Improved Soul Fire > Immolate > Conflagrate > BoD > Corruption > Shadowflame > Shadowburn > Chaos Bolt > Incinerate
To summarise, Conflag should be on cooldown as much as possible, as it provides Backdraft which reduces the cast time of Chaos Bolt, Shadow Bolt and Incinerate by 30%. As Shadow Bolt isn't really used due to Incinerate's bonus damage while Immolate is on the target, Incinerate is our filler spell, to be used when we can't use anything else. Soul Fire when procced by Firebolt should be kept if movement will be required in the next few seconds, else Fel Flame will be used and Soulburn will then be on cooldown from using an instant SF.
Demon Soul: Imp should be used pretty much on cooldown, as it will increase the crit chance of all our Destruction spells by 30%, you should only delay this if you're going to get a BL/TW/Heroism in the next 30 seconds or so, and as such it'll be of more use there.
So a possible opening would be to:
Prepot/Trinkets > Improved Soul Fire > CoE (while SF is in mid-air) > Immolate > Corruption > BoD > Demon Soul: Imp > Conflagrate > Shadowflame (If in melee) Chaos Bolt > Incinerate. And then following the rotation above.
Stats:
Destro has been simmed to be very much alike to Affliction, and as such follows this rule:
Intellect > Hit (Until 17%) > Spell Power > Haste > Crit = Mastery
Haste is particularly important to warlocks, as it increases the amount of ticks we get from dots and decreases cast times and our GCD (Only to a minimum of 1.0s GCD however). As you'll be using 3 different DoTs (excluding Burning Embers), the thresholds at which you gain an extra tick are useful to know, as it gives you a Haste target to work towards.
Immolate Extra Tick Thresholds: 9.9% - 30% - 49.9% - 70%
Corruption Extra Tick Thresholds: 8.3% - 25% - 41.7% - 58.4%
Bane of Agony Extra Tick Thresholds: 4.1% - 12.5% - 20.8% - 29.7% - 37.5% - 45.8% - 54.1%
However, the main thresholds you want to reach as Destruction are the Immolate Thresholds (above in bold), as these will give you higher immolate damage, thus increasing your Conflagration damage. 2589 Rating will give you a dps increase of around 1k, so hitting Immo Thresholds is the priority when looking at haste values. At a certain point (between 3100-3200 rating) haste loses a tonne of its value and mastery becomes king at this point, until around 3600-3700 Haste rating.
A full spreadsheet of the haste thresholds can be found here, thanks to Keldion on EJ
Reforging:
Easy way to figure out how to reforge for Destruction:
Am I hit capped?
If No: Reforge Mastery first, then Crit, to Hit.
If Yes: Reforge extra Hit to Haste
Does the item have Haste on it?
If Yes: Go to the next rule
If No: Reforge Mastery first, then crit, to haste
Reforge mastery to crit if the above has been done.
Any issues with this can be solved with two words... SIM IT!
Enchanting:
Head: Arcanum of Hyjal
Shoulders: Greater Inscription of Charged Lodestone
Back: Enchant Cloak - Greater Intellect
Chest: Enchant Chest - Peerless Stats
Wrists: Enchant Bracer - Mighty Intellect if available, otherwise Enchant Bracer - Precision
Hands: Enchant Gloves - Haste
Waist: Ebonsteel Belt Buckle
Legs: Powerful Enchanted Spellthread
Feet: Enchant Boots - Lavawalker or Enchant Boots - Precision or Enchant Boots - Haste
2-Handed Weapon or Main Hand Weapon: Enchant Weapon - Power Torrent
Off-hand: Enchant Off-Hand - Superior Intellect
Gems and Sockets:
Meta gem: Burning Shadowspirit Diamond
Red gem: Brilliant Inferno Ruby
Yellow gem: Reckless Ember Topaz
Blue gem: Veiled Demonseye
Gem Red. The only time you should deviate from this is either when:
1) The Socket bonus is 20+ Intellect
2) The Socket bonus is 30+ Haste/Crit
Else, you should stick to stacking red gems everywhere.
Professions:
Engineering: Synapse Springs provides 480 Int for 10 seconds with a 60 second CD. This averages to an 80 Int bonus. Tinkers stack with normal enchants.
Leatherworking: 130 Int to bracers in place of 50 Int, giving an estimated 80 Int bonus.
Jewelcrafting: 3 Brilliant Chimera's Eye in place of 3 Brilliant Inferno Ruby gives 81 Int.
Blacksmithing: Extra two sockets (Bracers/Belt) giving an estimated 80 Int bonus.
Alchemy: Mixology on top of Flask of the Draconic Mind will give an 80 Int bonus
Enchanting: two +40 Int enchants on rings, giving 80 Int Bonus.
Inscription: Felfire Inscription is an 80 Int bonus over the regular enchant.
Tailoring: Lightweave Embroidery provides 580 Int for 15 seconds on a 64 second ICD. This averages to 135.9 Int, which replaces the normal 50 Int enchant, providing only a 85.9 Int bonus. Tailoring currently gives the greatest DPS increase of all the professions.
Herbalism: Lifeblood is now a DPS cooldown providing 480 haste for 20 seconds on a 2 minute CD. This averages to an 80 haste bonus.
Skinning: 80 Crit rating.
Mining: Stam. Not useful in the slightest.
Pet:
As Destro, you want to be using your imp. If you pick anything else you are doing it wrong. For the following reasons:
1) Imp's Firebolt procs the Burning Embers talent, leaving a DoT on the target.
2) Imp's Firebolt procs Empowered Imp
A useful point to note is to macro your Imp's Firebolt to most of your abilities. This will help with target switching fights, meaning you'll get to pick what targets your pet is attacking constantly. It also reduces the actual downtime of your imp, so instead of the Imp waiting for your latency to kick in to cast another spell, it'll cast spells when you do. An example of a macro could be:
Which means your Imp will start happily casting Firebolt on the last target you cast spell X onto.#showtooltip SPELLNAME
/cast [@pettarget, exists] Firebolt
/cast SPELLNAME
Guardians:
As far as summoning Guardians go:
Boss/Single-Target: Summon Doomguard
Trash/Multi-Target: Summon Infernal
Make sure to have Bane of Agony/Doom up on a target to make sure these guys start attacking things the moment they've been summoned, else they'll stand around like lemons.
Consumables:
Potion: Volcanic Potion - If pre-potting, ask for a pull countdown and pop it 1-2 seconds before the pull, to ensure it starts the CD before combat starts. This will provide you with access to another potion during a nuke phase.
Flask: Flask of the Draconic Mind
Food: Severed Sagefish Head or Seafood Magnifique Feast
Make sure to pop Ritual of Souls before a fight to make sure everyone, including you, has a Healthstone. Also, remember to Create a Soulstone before a fight, as it can now be used as a combat res and shouldn't be wasted.
Useful Macros:
A few macros I find useful are:
Armorswap:
