 The alhoon also appeared in third edition in "Monsters of Faerûn" (2001) and "Lords of Madness" (2005).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.
