Squad Ace BU (Japanese: 第73迷宮の覇者 Champion of the seventy-third labyrinth) is a Sacred Seal skill which debuted in Fire Emblem Heroes; it exists in three tiers: Squad Ace BU 1, Squad Ace BU 2, and Squad Ace BU 3. Squad Ace BU is a combination of the HP + and Attack/Res skills, increasing the user's maximum HP, attack, and resistance; additionally, as it is not a duplicate of the HP + or Attack/Res seals, a unit may possess all seals at the same time.

The Squad Ace BU 1 seal may be obtained upon successful completion of the seventy-third Squad Assault challenge; it is one of the Sacred Seals that cannot be initially created through the Sacred Seal Forge. Tiers 2 and 3 must be obtained via forging in the Sacred Seal Forge.
