The cousin to the faun, with a more goat-like head and ill-tempered disposition
The Ibix is the cousin to the faun, with a head that is much more goat-like. Unlike fauns, an ibix is ill-tempered and generally considered evil, sometimes even allying with humanoids such as goblins. It has identical statistics to those listed above, except that it speaks Goblin rather than Halfling.
