Spiritron Dress

Spiritron Dress (霊衣開放), also known as Costume Change or Spiritual Costume Unlock, is the feature that lets a Servant change their outfit, thus changing their in-game art and battle sprite (and, in Astolfo's case, their Noble Phantasm). This was introduced with v1.25.0, and Mash Kyrielight was the first Servant to get an alternate outfit.

Alternate outfit/costume can be unlocked after a few conditions are cleared :

• Obtaining Wardrobe Key (霊衣開放権) by clearing designated quests or purchasing in shop. Note that you do not need to have the Servant to be able to purchase the Permit.
• Reaching a Level or Ascension Stage (varies among Servants)
• Having the required materials/items (varies among Servants)
