Half-illithid lizardfolk, called tzakandi in the illithid language, are used as slave laborers and personal guards in some illithid communities. Their appearance contains aspects of both the illithid and the host; no two of them look exactly the same.

Combat

Half-illithid lizardfolk are prized among their illithid masters for their vicious ferocity. Intelligent enough to put their psionic powers to best use, tzakandi generally work in pairs, one member using its mind blast on enemy spellcasters while the other wades into melee and protects its partner.

Psionics (Sp): 3/day⁠—​detect thoughts (Will save DC 15).

Skills: Thanks to their tails, half-illithid lizardfolk have a +4 racial bonus on Jump, Swim, and Balance checks.
