Okay, seriously, GM: if you're going to allow warlocks in your game, you NEED this supplement. This is just PACKED with information on how to GM a warlock. Stop letting warlocks just be a weirdo who couldn't decide if they wanted to be a wizard or a priest. Make being a warlock a unique, rich and fulfilling experience with THIS book. Lots of information, lots of new options (just look at the store page! It's all true). Absolute necessity for any GM who has a warlock in the party.
