At start of combat, if unit's HP ≥ 25%, inflicts penalty on foe's Atk/Spd/Def/Res = number of foes within 3 rows or 3 columns centered on unit × 3, + 5 (max 14; if unit triggers Savior, value is treated as 14), unit deals +X damage (excluding area-of-effect Specials), and reduces damage from foe's attacks by X during combat (excluding area-of-effect Specials; X = number of allies within 3 spaces of unit × 5; max 15; if unit triggers Savior, value is treated as 15), and also, if foe's attack can trigger foe's Special and unit's Res ≥ foe's Res+5, triggers the following effects during combat: inflicts Special cooldown count+1 on foe before foe's first attack and if foe's first attack triggers the "attacks twice" effect, inflicts Special cooldown count+1 on foe before foe's second strike as well (in either case, cannot exceed the foe's maximum Special cooldown). If unit's HP ≥ 25% at start of combat and unit's Special cooldown count is at its maximum value after combat, grants Special cooldown count-1 to unit after combat.

Notes

Attacks that "calculate damage using the lower of foe's Def or Res" include attacks during combat and area-of-effect Specials.

Sources of effects that disable "calculates damage using the lower of foe's Def or Res":

Rare Talent, Aureola, Radiant Aureola, and Light and Dark II will disable this effect during combat, but not against area-of-effect Specials.

Duskstone applies the Draconic Hex status effect.
- Any 【Bonus】 on a unit lasts until the start of that unit's next phase. If Draconic Hex is acquired during the enemy phase, it will disappear when the next player phase begins.

The stat decrease that can be applied by Draconic Hex is considered a temporary debuff.

Duskstone's cooldown count changing effect will not trigger if the unit is inflicted with False Start, unless False Start is removed by a skill such as Dream Deliverer.
Cooldown count changes from skills that activate at the same time as Duskstone (at start of turn) are not considered in Duskstone's conditions.^[1] Skills such as Infantry Pulse 4, Buffer 4, and Odd Pulse Tie 3 will have their effects stack.
The stat decrease that can be applied by Duskstone is considered a temporary debuff.

The damage boosting effect is a flat +X (max: 15) damage that ignores the foe's Def or Res when calculating the damage boost, and 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.
The damage-reduction effect is a flat -X (max: 15) damage that is calculated after offensive Specials, damage boosting effects such as Arcane Lúin and Dominance, and "reduces damage by X%" effects such as Gust and Dodge.
- 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.
- Flat damage-reduction effects stack additively, similar to 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 by effects such as Share Spoils or Halves non-Special damage reduction.
- For more information, see Damage calculation.
Duskstone's Special cooldown count increase that occurs during combat is a flat +1 and is not affected by effects related to Special cooldown charge such as Guard, Special Cooldown Charge +1, and Spd/Def Tempo 4.
- All flat cooldown count increases and/or reductions during combat will stack with each other if they trigger at the same time.
  - For example, if a unit has Preempt Pulse and Hush Spectrum, the effects will stack and the unit's cooldown count will neither increase nor decrease.
Duskstone triggers before after combat Specials such as Galeforce and Røkkr AoE Specials.
Cooldown count changes from skills that activate at the same time as Duskstone (after combat) are not considered in Duskstone's conditions. Skills such as Special Spiral 4, Time's Pulse 4, and Pulse Smog will have their effects stack.
