Immaterial and burrowed creatures are immune to all attacks and other effects. Burrowed creatures are effectively immaterial, but their attack strength is halved (rounded down) and they have the additional option to unburrow and regain their normal attack strength and vulnerabilities.

CreaturesEdit

Immaterial creatures cannot be targeted by other creatures or cards. For example, they are immune to individual attacks such as Lightning, Freeze, Otyugh, Parasite, Arctic Squid, Lobotomizer, and Maxwell's Demon, and to group attacks such as Thunderstorm and Plague.

However, they are affected by shields. They can be frozen by the Ice Shield, stopped by Procrastination, and damaged by Fire Shield.

They cannot be targeted by beneficial effects such as Blessing or the Guardian Angel's heal power. They can continue to use their own powers. For example, an immaterial Forest Spirit can still grow, and an immaterial Otyugh can still devour other creatures.
