Aberration is a creature type in Dungeons & Dragons.


Aberrations are alien entities with bizarre anatomy and strange abilities.[1] They are frequently connected to the Far Realm,[2] and many have mental powers.[3]

Examples of aberrations include aboleths, beholders, and mind flayers.[4] Slaadi are sometimes classified as aberrations.[3]
