- Affliction
- Demonology
- Destruction
Although all the three trees can enhance the damage power of the Warlocks, the playstyle of the warlocks of each specs can be very different. Affliction increases the power of the warlock's curses and damage over time spells. Demonology helps the endurance of the warlocks, by splitting damage taken with pets and better buffs from their pets, by either keeping it active or sacrificing it. Finally, Destruction allows for a mage-style of playing by improving their direct damage spells. Warlocks are widely considered to be one of the, if not the best one-on-one PvP class in the game.
