Description [ExpandCollapse]	Accelerates Special trigger (cooldown count-1). At start of turn, if unit's HP ≥ 25%, grants Atk/Spd+6,【Potent Follow】, and "neutralizes foe's bonuses during combat" to unit and allies within 2 spaces of unit for 1 turn. At start of combat, if unit's HP ≥ 25%, grants bonus to unit's Atk/Spd/Def/Res = 5 + 15% of unit's Spd at start of combat, and also, if【Potent Follow X%】has triggered and X ≤ 99, then X = 100, unit deals +Y × 5 damage (Y = number of Bonus effects active on unit, excluding stat bonuses + number of Penalty effects active on foe, excluding stat penalties; max 5; excluding area-of-effect Specials), and reduces damage from foe's first attack by Y × 3 during combat ("first attack" normally means only the first strike; for effects that grant "unit attacks twice," it means the first and second strikes), and also, when foe's attack triggers foe's Special, reduces damage by Y × 3 (excluding area-of-effect Specials). At start of combat, if unit's HP ≥ 25%, restores 7 HP to unit after combat.	Accelerates Special trigger (cooldown count-1).

At start of combat, if unit's HP ≥ 25%, restores 7 HP to unit after combat. 【Potent Follow】 If decreasing the Spd difference necessary to make a follow-up attack by 25 would allow unit to trigger a follow-up attack (excluding guaranteed or prevented follow-ups), triggers【Potent Follow X%】during combat (if unit cannot perform follow-up and attack twice, X = 80; otherwise, X = 40). 【Potent Follow X%】 Triggers an additional follow-up attack immediately after unit's standard follow-up attack and deals damage = X% of unit's normal attack damage (if unit cannot make a follow-up attack, this effect triggers when the standard follow-up attack would occur; this effect is treated like a follow-up attack, so effects like "reduce damage by X%" still apply, but this effect is not affected by effects that prevent follow-ups or "attacks twice" effects; only highest value applied; does not stack).

Notes[]

The stat increase that can be applied by Sword of Isaach is considered a Bonus.
- Any 【Bonus】 on a unit, including Bonuses, lasts until the start of that unit's next phase. If Bonuses are acquired during the enemy phase, they will disappear when the next player phase begins.

Sword of Isaach applies the Potent Follow status effect.
- Any 【Bonus】 on a unit lasts until the start of that unit's next phase. If Potent Follow is acquired during the enemy phase, it will disappear when the next player phase begins.
- Potent Follow allows the user to perform an additional follow-up attack immediately after the standard follow-up attack (or in the place of the standard follow-up if the unit cannot perform one).
  - Effects that prevent follow-up attacks such as Weaving Fighter or Foe Cannot Follow-Up will not prevent the additional follow-up attack granted by Potent Follow.
  - "Unit attacks twice" effects such as Brave Sword+ or Triangle Attack will not double the additional follow-up attack granted by Potent Follow.
  - A foe with effects such as Phys. Null Follow or Null Follow-Up will not neutralize the additional follow-up attack granted by Potent Follow.
- The damage boosting effect of Potent Follow 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.
Sword of Isaach applies the Neutralize Bonuses status effect.
- Any 【Bonus】 on a unit lasts until the start of that unit's next phase. If Neutralize Bonuses is acquired during the enemy phase, it will disappear when the next player phase begins.

Neutralize Bonuses can neutralize Bonuses during combat.
- 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 stat increase that can be applied by Sword of Isaach 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.

The damage boosting effect is a flat +X (max: 25) 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.
The damage boost and flat damage reduction of Sword of Isaach will activate if the user receives a 【Bonus】 (excluding Bonuses).
- The damage boost and flat damage reduction will not be negated if the unit receives a 【Penalty】.
- If the unit does not receive a 【Bonus】 (excluding Bonuses), or has their 【Bonus】 removed by a source of positive status effect neutralization, the damage boost and flat damage reduction will be negated.
- For more information, see Status effects.
The damage boost and flat damage reduction of Sword of Isaach will activate if the foe receives a 【Penalty】 (excluding Penalties).
- The damage boost and flat damage reduction will not be negated if the foe receives a 【Bonus】.
- If the foe does not receive a 【Penalty】 (excluding Penalties), or has their 【Penalty】 removed by a source of negative status effect neutralization, the damage boost and flat damage reduction will be negated.
- For more information, see Status effects.

The healing effect is triggered regardless of whether Sword of Isaach's user performs an attack during combat. If foe initiates combat and user cannot counterattack, Sword of Isaach's healing effect will still trigger.
Sword of Isaach's user needs to survive the combat for the healing effect to trigger.
Sword of Isaach's healing effect stacks with skills such as Fury 4, that deal out of combat damage to their owner after combat.
Sword of Isaach'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.
