Can I play a vampire/werewolf/lich/ghost/angry manimal/etc.?
We have monstrous templates that can be given to PCs if they role-play well and are in the proper in-game circumstances to cause such a transformation to occur. Monster races are templates that are applied to existing PCs, and are usually the result of a curse, a series of failed powers checks or some incident involving other monsters of the same type. Do not beg to play one — this will guarantee that you will not get it. You can find the application for monstrous races here.
