Note[ | ]

The stat increase that can be applied by Arcane Sly Knife is considered a temporary buff.
A stat comparison made "At start of combat" ignores temporary buffs and temporary debuffs.
- Temporary buffs and temporary debuffs from skills such as Death Blow and Rauðrfox+ will not affect the outcome.
- Only stat boosts outside of combat, such as Bonuses and Penalties, will affect the outcome.
Arcane Sly Knife can neutralize Bonuses.
- Bonuses are neutralized by inflicting temporary debuffs of the same amount during combat.
- The Bonus neutralizing effect will be negated if the affected unit has Panic (and doesn't have Null Panic), or has their Bonuses removed by a source of positive status effect neutralization.

The damage boosting effect of Arcane Sly Knife is not affected by the weapon-triangle, and includes the increased Atk from skills like Blárblade+ in its calculations.
The damage boosting effect of Arcane Sly Knife 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 -7 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.
Arcane Sly Knife's Special cooldown count reduction 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.
