Stance Change allows Aegislash to switch between Shield Forme (high defensive stats, low offensive stats) and Blade Forme (high offensive stats, low defensive stats). Aegislash is always in Shield Forme if it is not battling, and as such, switching out reverts it to Shield Forme. It changes to Blade Forme when using a damaging move, and reverts to Shield Forme when using King’s Shield. Status moves other than King’s Shield will not change its form. Moves that call other moves, such as Sleep Talk, will not change Aegislash’s Forme, even if they call a damaging move or King’s Shield.
The Ability activates prior to and independently of any checks for status conditions that may stop the execution of the user’s attack, such as sleep or confusion.
Stance Change cannot be Traced, copied with Role Play, suppressed withGastro Acid, or replaced with Simple Beam, Worry Seed, Entrainment, Skill Swap, or Mummy. If a Pokemon other than Aegislash obtains Stance Change with Imposter or Transform, the Pokemon will not change Formes.
Outside of battle
It is unknown if Stance Change has an effect outside of battle.
