Aegis - Aegis protects a unit or player from one enemy spell or effect. It doesn't block friendly effects, nor does it stop battle damage from Killer attacks, Relic Weapons, or normal attacking and blocking.

Mastery - All damage dealt by units with Mastery count towards its Mastery ability. When its Mastery number is met, it uses its Mastery ability.

Exalted - When a unit with Exalted dies, play a weapon with its strength, health, and other battle skills on one of your units.
