Acromae Elmhden, Pathfinder summoner, synthesist archetype. Artwork of her while fused with her eidolon. Course like, this won't remain accurate as more evolutions pile onto the eidolon, this is the form that will represent what it would look like on her entry into her respective game at her level.

Why yes, that is a paw coming out of her split-open palm.

PG 13 for moderate unpleasantness, body horror and intentional trypophobia.
