Create Aberration

Create Aberration is a spellcasting feat for the forging together of two or more creatures in the creation of a single aberration blending their abilities. The terms of the feat stipulate that for "pure hubris and perversion" the spellcaster courts the attention of the Dark Powers. A druid may not take this feat given its unnatural spawn.
