Some times a players race may change, or they may be affected by a curse. This may occur by being bitten by a werewolf, or by drinking the wrong potion.
In either case, all known templates will be kept here.
All are Racial adjustments, however becoming one, grants you access to the related prestige class as well, should you choose to advance as that. Each of these classes advances the powers given by the transformation. There are 5 levels for each, when you reach level 5, you may be able to transform into a more powerful version of your creature, eg. werewolf becoming a wolflord, or lich becoming a demilich.
