Notes

• The stat boost that can be applied during combat by Dual Support is considered a temporary buff.

• The damage boosting effect is a flat +1/2/3/5 damage that ignores the foe's Def or Res when calculating the damage boost, and can be reduced by damage reduction effects such as  Archrival,  A/S Rival Break, and  Dodge.
  • Damage boosting effects stack additively, similar to flat damage-reduction effects and interactions related to the weapon-triangle, such as  Triangle Adept and the weapon-triangle advantage boost.
  • A foe equipped with Invincibility Seals will neutralize all sources of damage except from Røkkr area-of-effect Specials and the minimum 1 damage from Umbra Burst weapons.
  • A foe using attack damage preventing effects can neutralize damage dealt from the foe's own attacks and the unit's attacks (Units with Umbra Burst weapons will take and deal the minimum 1 damage).
  • For more information, see Damage calculation.
• The flat damage-reduction effect is a flat -1/2/3/5 damage that is calculated after offensive Specials, damage boosting effects such as  Arcane Thorn and  Change of Fate, and "reduces damage by X%" effects such as  Archrival and  Dodge.
  • If a an effect such as  Miracle or  Roy: Of Binding's boosted Special effect can trigger, the damage-reduction effect will not trigger and the user will still survive with only 1 HP.
  • Umbra Burst weapons will always deal a minimum of 1 damage even if the foe uses attack damage preventing effects, Invincibility Seals, or damage reduction effects.
  • Flat damage-reduction effects stack additively, similar to damage boosting effects and interactions related to the weapon-triangle, such as  Triangle Adept and the weapon-triangle advantage boost.
  • Flat damage-reduction effects cannot be neutralized or reduced only during combat by effects such as  Share Spoils+ or  Halves non-Special damage reduction.
  • For more information, see Damage calculation.
• The temporary buffs, damage boost and damage reduction effects of Dual Support will not apply to the user's allies if the user is inflicted with  Time's Grip, the user's allies are inflicted with  Feud, or the user's allies are in combat against a foe with skills such as  Impenetrable Void and  C Feud 3.
• Dual Support will neutralize the "Special cooldown charge +X" effect on foes from effects such as  Heavy Blade 4,  Special Cooldown Charge +1, or the Grand Conquests  Infantry area effect.
  • Since the "Special cooldown charge +X" effect will be neutralized on foes, Dual Support will also stack with the "Special cooldown charge -X" effect inflicted on the foe from effects such as  Guard Sword+,  Guard, or  【Divine Vein (Vert)】, unless the foe is equipped with skills that neutralize the "Special cooldown charge -X" effect on unit.
• Dual Support will neutralize the "Special cooldown charge -X" effect on unit from effects such as  Guard Sword+,  Guard, or  【Divine Vein (Vert)】.
  • Since the "Special cooldown charge -X" effect will be neutralized on unit, Dual Support will also stack with the "Special cooldown charge +X" effect on unit from effects such as  Heavy Blade 4,  Special Cooldown Charge +1, or the Grand Conquests  Infantry area effect, unless the foe is equipped with skills that neutralize the "Special cooldown charge +X" effect on unit.
• The special cooldown charge -X neutralization of Dual Support 4 will not apply to the user's allies if the user is inflicted with  Time's Grip, the user's allies are inflicted with  Feud, or the user's allies are in combat against a foe with skills such as  Impenetrable Void and  C Feud 3.
• The special cooldown charge +X neutralization of Dual Support 4 will not apply if an ally enters combat and the user is inflicted with  Time's Grip, the ally is inflicted with  Feud, or the ally is in combat against a foe with skills such as  Impenetrable Void and  C Feud 3.
