Description Grants Spd+3. If unit's Spd > foe's Spd, deals damage = 70% of difference between stats. (Maximum bonus of +7 damage. Combos with Phantom Spd.) At start of turn, if unit is adjacent to only beast or dragon allies or if unit is not adjacent to any ally, unit transforms (otherwise, unit reverts). If unit transforms, unit can move 1 extra space. (That turn only. Does not stack.) If unit transforms, grants Atk+2.


  • The maximum Spd difference that matters for Raven King Beak's damage bonus is 10, due to Raven King Beak's cap of 7 bonus damage.
  • The minimum Spd difference that matters for Raven King Beak's damage bonus is 2, which provides 1 bonus damage.
  • The bonus damage from Raven King Beak is applied after other effects, and is thus not boosted by specials such as Icon Skill Special.png Glimmer or Icon Skill Special.png Astra.
  • With Phantom Spd 3.png Phantom Spd 3, Raven King Beak will deal extra damage if the user would otherwise have equal or less Res than the target.
    • This effect stops when the user is regularly 9 Spd slower than the target, as a 1-Spd advantage rounds down to zero damage.

  • The Atk+2 granted by Raven King Beak when the user transforms is a stat boost, not a  bonus.
