Now, assuming you have at least looked through a guide you will know that this is a PvP styled fight against either 6 (10 man) or 10 (25 man) player-style NPCs of the opposing faction. If you dislike PvP then do not worry, although many of the game mechanics of PvP are at play (diminishing returns for example) the bosses are still reasonably predictable and manageable. You certainly don't need to go out and get yourself any PvP gear.
As a lock, your role in this fight is either going to come down to damage application or mitigation. If it's damage application for you, then you need to know who is the current target at all times. There is no point trying to burn a load of them down with area effect spells because of Champion's Aegis which means they only take 25% damage from AoE spells. Applying heavy damage from the start makes a big difference so be ready for a Bloodlust or Heroism to be coming your way early.
The first target is likely to be a healer, burning them to a crisp as quickly as possible is the key to making the rest of the fight easier from there. You can throw in fears and Death Coil if you like as they will interrupt casts. Generally it's better to leave the interruption up to the melee classes however, as fear takes too long to cast (costs too much DPS) and Death Coil will just make everyone have to move. You're there to nuke, so revel in it and let those others do the fiddly stuff.
Should your raid lead call for you to get involved in the fiddly CC stuff as well there is quite a bit you can do. In normal mode they all forgot to bring their PvP trinkets -- so fear will sit on most of them for good while as long as they haven't been feared recently and nobody clears it from them. You can go so far as to make macros like the following and key-bind them for use at good moments within your rotation or while finding the next target.
/tar Noozle Whizzlestick
/y Tell Belt, he's next!
Obviously not all the lines of that macro are required but feel free to edit as you see fit. You can also banish the warlock's pet
which can be pretty worthwhile. In our raids we kill the pets after the healers as they die very quickly and it eases things up a bit, but banishing works if you get it biting your behind.
One of the juiciest targets for warlock crowd control is the resto druid
. His healing is really quite powerful which makes him a common first target but if a warlock gets a hold on him he can be effectively removed from the fight and dealt with at the raid's leisure. Chaining Fear
three times, which will diminish from a decent duration to essentially an interrupt, then swap to Banish
(who doesn't love banishing trees?) for another three. There you can either throw a Death Coil
if available and start again. He'll still get out some instant cast HoTs but they can be stolen
from the target, so all good.
Beyond that it's a matter of survival, so keep your Circle
up and use it as required (escaping a whirl-winding warrior
or clearing snares), use your PvP trinket or Every Man for Himself
and be aware of when you get aggro (often when one targets you the others will assist them). Your healers should be able to deal with it but be ready to move or maybe cast Howl of Terror
if they come for you.
Pet choice is a little more fluid for this fight, the imp is great for the stamina and Destro locks will probably want to keep theirs. Felhunters are very handy to have around and as a Demonic Pact
lock I find they are just about as good for uptime. The Felguard is great for damage and the Intercept
is also fairly handy. Faction Champions loot
