Great Aether

Name	Cooldown	Description	SP	Required
Great Aether	4	When Special triggers, boosts damage by percentage of unit's Atk = number of times foe has attacked during this combat × 10, + 40. If unit initiates combat, foe can counterattack before unit's first attack. If foe can perform a follow-up attack, foe can make a follow-up attack before unit's next attack during combat. Reduces damage from attacks by percentage = 40, - current Special cooldown count value × 10 during combat, but if unit receives consecutive attacks, reduces damage from foe's second attack onward by percentage = 70, - current Special cooldown count value × 10. If this Special is triggered during combat, deals 5 damage to foes within 3 rows or 3 columns centered on unit, inflicts Special cooldown count+1 (cannot exceed the foe's maximum Special cooldown) on those foes, and restores X HP to unit after combat (X = number of foes within 3 rows or 3 columns centered on unit × 5, + 10; max: 50% of unit's max HP).	500	Sol Luna
This skill can only be equipped by its original unit.

The Special damage boosting effect of Great Aether can be reduced by damage-reduction effects such as Gust, Atk/Spd Excel, and Dodge.
- A foe equipped with Embla's Ward, Múspellflame, Niðavellir Axiom, Gold Perfection, or Nine-Realm Pact will neutralize all sources of damage except from Røkkr area-of-effect Specials and the minimum 1 damage from Umbra Burst weapons.
- For more information, see Damage calculation.

"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.
Great Aether does not grant the foe the ability to counterattack regardless of user's range.
If the foe can counterattack, either from using a weapon with the same range as the user's weapon or from countering skills, the foe's counterattack will occur before the user's initial attack.
Great Aether changes the priority, or order of attacks, and therefore can be neutralized by effects such as Hardy Bearing 3 or Armorpin Dagger+.
"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.
Great Aether 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 Great Aether's priority changing effect.

The damage-reduction effect is calculated after offensive Specials and damage boosting effects such as Arcane Lúin and Dominance.
- 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.
- "Reduces damage by X%" effects stack multiplicatively, unlike interactions related to the weapon-triangle, such as Triangle Adept and the weapon-triangle advantage boost.
  - 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.
- Special "reduces damage by X%" effects cannot be neutralized or reduced by effects such as Share Spoils or Halves non-Special damage reduction.
- For more information, see Damage calculation.
Great Aether inflicts out of combat damage.
- Out of combat damage cannot reduce a unit's HP to 0.
- A foe equipped with Embla's Ward, Múspellflame, Niðavellir Axiom, Gold Perfection, or Nine-Realm Pact will neutralize all sources of out of combat damage except from Røkkr area-of-effect Specials.
- A foe equipped with Røkkr or a unit with En Garde will neutralize all sources of out of combat damage except Area-of-effect Specials.

The healing effect is triggered regardless of whether Great Aether's user performs an attack during combat. If foe initiates combat and user cannot counterattack, Great Aether's healing effect will still trigger.
Great Aether's user needs to survive the combat for the healing effect to trigger.
Great Aether's healing effect stacks with skills such as Fury 4, that deal out of combat damage to their owner after combat.
Great Aether's after combat healing will not work if the foe has a skill that prevents HP recovery such as Fatal Smoke 4 or Incurable+, or the user has been inflicted with Deep Wounds.
