If unit initiates combat or foe's Range = 2, inflicts Atk/Res-10 on foe during combat, unit makes a guaranteed follow-up attack, and also, if unit receives consecutive attacks, reduces damage from foe's second attack onward by 80%. If foe with Range = 2 initiates combat and foe can make a follow-up attack, foe makes a follow-up attack before unit can counterattack.
This skill can only be equipped by its original unit.
"If unit initiates combat" means if the user starts combat during the player phase. The unit does not need to deal damage, nor be the first to attack.
However, if the effect is applied after combat, the unit must also survive it to fulfill this condition.
The stat reduction that can be applied during combat by Gift of Magic is considered a temporary debuff.
As a general rule, if a unit is both prevented from making, and guaranteed to make a follow-up attack, the effects cancel out, and the Spd difference decides instead (including effects that alter the Spd difference such as Frozen).
A foe with effects such as Phys. Null Follow or Null Follow-Up will neutralize the guaranteed follow-up attack granted by Gift of Magic.
If a skill such as Miracle or Everliving Domain can trigger, the damage-reduction effect will not trigger and the user will still survive with only 1 HP.
For example, if both Dodge and Gust trigger, the maximum total damage-reduction is 64% instead of 80%, since the two skills reduce the damage to (1 − 40%) × (1 − 40%) = 36% of the original damage.
"If foe initiates combat" means if a foe triggers combat during the enemy phase. The unit being initiated upon does not need to deal damage, nor be able to counterattack.
However, if the effect is applied after combat, the unit being initiated upon must also survive it to fulfill this condition.
Gift of Magic does not guarantee the foe a follow-up.
If the foe can perform a follow-up, either by passing the Spd difference check or from guaranteed follow-up effects, the initial attack and follow-up will occur before the user can perform a counterattack.
Effects such as Vantage or Paranoia have priority over Gift of Magic's priority changing effect.
