Drain Hunting
Minimum Level: 14
Mandatory Talents: Improved Corruption, Soul Siphon, Improved Life Tap, Fel Concentration, Empowered Corruption
Boosting Talents: Siphon Life, end-game build of SM/ruin or full Affliction, improved VoidWalker and fel stamina for demonologists
Description:
The idea of this techinque is to destroy mobs while losing as little life and mana as possible. A good Drainhunter has little or no downtime. The main thrust of drainhunting is to let your Voidwalker engage the mobs while you dot them, lifetap, and drain them. In general, the cast sequence is (send in the VW), DoT, DoT, DoT, Lifetap, Drain Life - wand if necessary. If you are farming shards, finishing with Drain Soul is a good idea. Since you want to keep aggro on your Voidwalker, give the VW enough time with the mobs to taunt them twice before your first cast. This technique allows you to have your demon engage several monsters at once. DoTs + Drain bring down mobs very fast. Throw the dots with the LEAST damage first (Curse of Agony, Corruption) before tossing an immolate, so you don't draw aggro from your VW. If you encounter a runner, Curse of Recklessness thrown after Drain life will keep them on the Voidwalker. After a battle against multiple mobs, let your Voidy Consume Shadows to regain health. Also, if you are at full life but not on mana, Life Tap after a battle (this is probably good advise for all techniques, not just Drainhunting).

Drain Tanking
Minimum level: 23-24
Mandatory Talents: 5/5 Fel Concentration
Boosting Talents: 2/2 Soul Siphon, 1/5 Shadow Embrace, 2/2 Nightfall, 1/1 Siphon Life
Description:
This is the reverse to Hunterlocking: aside from the opening moves, the warlock is tanking instead of the pet. The technique is again deceptively simple: send your pet, cast your dots, life tap, drain life. If you have Nightfall, cast your instant shadowbolts at the end of a drain life. The point though, is that instead of using the voidwalker and casting with finesse, you will strive to get the monster turn on you once you're done casting your DoTs and life tap. To speed up damage output you will use a succubus or, situationally, a felhunter as your primary pet. In general, to maximize exp / hour, you will mainyl concentrate on monsters 2-3 levels below yours (whereas drain hunting would allow you to fight higher stuff) and avoid getting more than 1 add. In the later levels, though, this is enough to take on yellow elites without breaking too much of a sweat.
