Ulitharid

Ulitharids are created from tadpoles much like standard illithids; fewer than 0.1% become ulitharids, and it is impossible to determine whether a tadpole will become an ulitharid until ceremorphosis is complete.

Superior in nearly all ways to a regular mind flayer, ulitharids possess two extra tentacles, which are twice as long as the others, and an extreme arrogance, even by the standards of their own kind. Only the elder brain holds more sway within an illithid community.
