Getting Infernal and DoomguardFollow

infernal u get from chain quest in felwood, just above blood venom falls or something like that, and doomguard u get if u kill something using curse of doom

Infernal and Doomguard are (essentially) toys.

I *HATE* to say it (because I always wanted them before I actually got to see what they were like), but you won't use them much at all. If you want a powerful doomguard or infernal pet, I would search for areas with Elite demons around your level and go out and enslave one.

The ONLY use I've really found for the infernal is as a 2-second cast AOE stun (a poor man's shadowfury). The doomguard's ritual nobody will do with you, and when you do happen to summon one with CoD, it's just as likely to gank you as it is to become your uberpet for 5 mins.

Here are the links to both quests:

Infernal Quest Chain:

Doomguard Quest Chain:

You must first do two gathering quests before you can do the final Doomguard quest.

Step 1
Step 2
And finally the end quest:
The Suppression

NOTE: Like most have already said both pets are novelty pets...you wont use them much if ever. Its really just a way to say hey i'm a warlock look what i can do.

I just used my first real infernal the other day to take out an elite a couple levels higher than me. Worked like a charm. That bad boy held aggro very well and when the fight was over he had little health left so I sent him after a few mobs and ran away. (the very first one I summoned killed me so he scares me now).

I think he will be my elite basher from now on instead of my VW, especially for those elites that are immune to fear.

So now for those 5 minuts you have the pet before it breaks free and kills you you can have your buffs. the problem is that when you loose controle of the summoned baddie, you loose the buffs, so they have not fixed this at all even if they add SL and DK buffs.
