Obscurantia offers the possibility to choose between 6 classes with unique and shared abilities. As the levels go by, each class unlocks active feats that require an average of 3 abilities in order to obtain maximum power. Several of these gifts are shared with classes that use one or two similar abilities. It is possible to develop your character in multiple ways in order to maximize a strategy. For purists, a character faithful to a single class will be granted a higher power of active feats for the recommended abilities of this class.
