Spell rotation

warlocks use this spell rotation:
destro spec :

your raid curse(CoS/CoE/Weak/Reck)-> corruption -> shadowbolt till mob/boss death

If you see on omen that you will overagro on mob go to offtank target for 2 shots then come back to main target. On pull you can dont use corruption if mob will gain +-5k agro from tank.

You should have at least 25% crit with talents/buffs to have this effective and you should try to get 33%crit.

NO MORE FIRE DMG - you have at least 25% more shadow dmg on items/talents than fire dmg

affliction spec:

your raid curse(CoS/CoE/Weak/Reck)-> corruption -> unstable affliction -> immolate -> siphon life -> shadowbolt and reaply DoT when needed

you should have tier4 first set bonus chance on hit to get +135 dmg, and trinket from heroic mgt - change to hit 450-500dmg on dot hit. This can proc very often if you are using as many dots as possible.

You have to also get Medalion of Karabor ASAP, it makes big difference on 2nd and 3rd boss in mh.

All warlocks please write that you read it and understand it, if you have any suggestions we can speak about it.

Rainbowflame : read it

i'd like to point out quite a few guides suggest that you shouldnt even put siphen life on, unless low on hp,..,,

also affl you might as well dot all tanked mobs on trash.

Also what if your a hybrid sm/ruin sort of spec, what should the spellrotation then be?

Tbh I didn't write this myself but shamelessly ninjaed it from a very informed Wlock that I was in guild with earlier on ^^

So I wouldn't know
