Toxic Spores. Although deathcaps are mostly peaceful, their spores are toxic and sleep-inducing. They make excellent allies in combat because their abilities tend to punish attackers, but they aren't especially lethal on their own. They use their poison and slumber spores to full effect against living creatures; they typically flee from constructs and undead. They count on their allies (carrion beetles, darakhul, purple worms, dark creepers, or even various devils) to fend off the most powerful foes.
