Aberrant Eidolon

Your eidolon is a terrifying, incomprehensible nightmare patterned after the creatures who owe their existence to the Outer Gods and Great Old Ones. Aberrant eidolons come in a variety of forms, though their anatomies often appear twisted and impossible. Most people can't even look at any aberrant eidolon without developing a splitting headache or having a panic attack, but your studies of the occult have inured your mind to these dread terrors.
