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.) If unit's Spd > foe's Spd, reduces damage from attacks during combat and from area-of-effect Specials (excluding Røkkr area-of-effect Specials) by percentage = difference between stats × 4 (max 40%).

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, grants Atk+2, and if unit initiates combat, inflicts Atk/Def-4 on foe during combat and foe cannot make a follow-up attack.


  • The maximum Spd difference that matters for Guardian Fang's damage bonus is 10, due to Guardian Fang's cap of 7 bonus damage.
  • The minimum Spd difference that matters for Guardian Fang's damage bonus is 2, which provides 1 bonus damage.
  • The bonus damage from Guardian Fang is applied after other effects, and is thus not boosted by specials such as Skilliconspecial.png Glimmer or Skilliconspecial.png Astra.
  • With Phantom Spd 3.png Phantom Spd 3, Guardian Fang 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 damage-reduction is calculated after offensive Specials and skills that deal extra damage, such as Icon Class Red Sword.png Wo Dao+.
    • Percentage-based damage-reduction effects stack multiplicatively, unlike interactions related to the weapon-triangle, such as gem weapons and  Triangle Adept.
      • For example, if both Spurn 3.png Spurn 3 and Skilliconspecial.png Vital Astra activate, the maximum total damage-reduction is 58% instead of 70%, since the two skills reduce the damage to (1 − 40%) × (1 − 30%) = 42% of the original damage.
    • For more information, see Damage calculation.
  • Skilliconspecial.png Deadeye, Skilliconspecial.png Lethality, Skilliconspecial.png Sublime Heaven, and Skilliconspecial.png Twin Blades will neutralize Guardian Fang's damage-reduction effect.
  • When used with offensive Specials, Skilliconweapon.png Bow of Frelia, Icon Class Red Sword.png Lioness Blade, Icon Class Colorless Tome.png Thunderer Tome, and Icon Class Red Sword.png Lands Sword will neutralize Guardian Fang's damage-reduction effect.
  • Icon Class Colorless Tome.png Adroit War Tome and Icon Class Red Tome.png Þjálfi can reduce the damage-reduction of Guardian Fang by 50%.
  • Beast refers to .
  • Dragon refers to .
  • The stat decrease that can be applied by Guardian Fang is considered a combat reduction.
  • Guardian Fang can prevent the foe from making a follow-up attack.
  • The Atk+2 granted by Guardian Fang when the user transforms is a stat boost, not a  bonus.
    • The stat boost, combat reductions, and follow-up preventing effects of Guardian Fang will only trigger if the unit is transformed.
