Initiate Seal Attack (Japanese: 鍛錬の証・攻撃???) is a Sacred Seal skill, which debuted in Fire Emblem Heroes. It exists in a three-tiered form, with the tiers respectively being named Initiate Seal Atk 1, Initiate Seal Atk 2, and Initiate Seal Atk 3. The seal is functionally identical to the Attack + skill, simply increasing the unit's maximum Attack by one point while equipped and not enhanced at the Sacred Seal Forge; however, it is not counted by the game as a duplicate of the Attack + seal or the functionally identical Squad Ace E seal, and so the player may legally possess all of these seals at the same time.
