The Netherbrain speaks through the rats in unison.
Combat
Cranium Rats will become temporarily hostile when wandering too close to the Morphic Pool Dock before obtaining all three Netherstones.
Attacking a Cranium Rat will engage their passive feature Infectious Madness, and possibly cause Confusion in the attacker. This passive will not be triggered when attacking with area spells like Fireball.
