Warlock trainers

A warlock trainer is an NPC that offers Warlocks training of their spells and abilities.

In addition to warlock trainers, some locations also hold Demon Trainers. Prior to patch 3.0.2, these were actually vendors of grimoires, used for training demon pets. Grimoires are not available anymore, since all demon abilities and spells will automatically be learned as pets gain levels. As of Patch 4.0.3a, the demon trainers instead offer the opportunity to randomly generate a new name for any of their primary demons at a cost of 50 a time per minion.
