Ulitharids don't use magic. Magic is almost banned in Illithid society. The rely mostly on me mental abilities. It use true that Ulitharids are physically monstrous but they lack effective fighting skills because they use their mental abilities a majority of the time. I should also point out undead are completely immune to their mental abilities. I'll change a few things though. Or atleast add some weaknesses. I should also point out that those with strong will can resist being mentally effected.
