@wencm1 I don't think he has that option yet

@wencm1 I think he lost access to the language skill when he abandoned the humanoid evolution lines and became a berserker chimera, as for telepathy, it probably isn't available yet, or it costs a lot more SP than he has.

@wencm1 He had to choose the evolution path of an evil monster. Does guys don't really comunicate to the people they attack

@wencm1 he never had a language skill, it was the cardinal from before that was using telepathy on Zoe, and as Valtruin states he did abandon the humanoid evolution line and thus lost access to another way to actually speak or communicate
