General information

Brains are looters, and so they loot harvesters more efficiently than most monsters (4x faster and 20% more). Brain is the last looter unlocked (not including Inferno). A level 1 Brain's health and damage is 4x stronger than a level 3 Bolt. Level 1 Brain Health = 600, Damage = 100; Level 3 Bolt Health = 150, Damage = 25.

Brain is used to feed level 2-6 Fomor.


Brain Invisibility

Brain's special ability Invisibility

Brain's Special Ability is Invisibility. It prevents him from being detected, and therefore can't be hit by defensive towers or monsters. Brain remains invisible until he attacks, then he can only stay cloaked for a short amount of time. How long depends on the training level of the ability. In housing, the Brain will be invisible. Invisible Brains are transparent blue with a very slight tint of its normal colors.
