A warlock in our guild who is a Demonology buff has been using my services to use what is probably, ok definitely, an expoit. Here's how it works.
The warlock uses Demonic Sacrifice to sacrifice his pet, which gives the warlock a 30 minute buff depending on what pet he sacrificed as follows:
1. Imp: Increases fire damage by 15%
2. Voidwalker: Restores 3% of total health every 4 seconds (180 health restored every 4 seconds for this warlock in question)
3. Succubus: Increases shadow damage by 15%
4. Felhunter: Restores 2% of mana every 4 seconds
This buff lasts 30 minutes or until the warlock summons another demon. So far, no exploit. OK, now comes the exploit part: A priest, shaman, or paladin can resurrect the demon and the warlock doesn't lose the Demonic Sacrifice buff. It's a little tricky, though, because resurrection takes 10 seconds and the demon corpses will despawn after 10 seconds. The resurrecter has to be ready to cast resurrect on the demon within a second (maybe half a second) of the moment the warlock sacrifices his pet. Basically, you have to cast resurrect on the demon while it's still in its death animation. Otherwise, the demon's corpse will despawn before it gets resurrected.
This is a major exploit. Consider when the warlock uses a voidwalker for this, as our guild's warlock often does. He gets the voidwalker sacrifice buff, plus he can use Master Demonologist to reduce all damage by 10% and use Soul Link to share 30% of all damage taken with the voidwalker. The warlock how has over 6k health with -40% damage taken and heals for 180 health every 4 seconds. Basically, the man is practically invulnerable in this setup. (He could even take one of Vendetta's pyroblast hits!).
The other option he sometimes breaks out when he wants to deal more damage is to sacrifice a succubus. This boosts his shadow damage by 15%. Plus, he can use Master Demonologist to increase his and his succubus's damage by 10% and still use Soul Link to share some damage with his succubus.
