Fiend Saws arts
Fiend Saws comes with a base art, a Tempering art and a Power Surge art. Four more unlock as you raise the weapon’s level. The Power Surge art, Fiend Form, costs 1 Sha-Chi Essence. The Power Surge breakdown covers how that system works.
| Art | Unlocks | Effect |
|---|---|---|
| Fiend-Aura Erosion | Base art | “Each hit builds up [Fiend-Aura Erosion] on the enemy. When the [Fiend-Aura Erosion] Gauge is full, the accumulated fiend-aura erupts, eroding the enemy’s HP.” |
| Endless Fiend Form | Tempering art | “After Fiend-Aura Erosion erupts on an enemy, all attacks against them become unblockable for 3 seconds.” |
| Fiend Form | Power Surge art (costs 1 Sha-Chi Essence) | “[Power Surge] Consumes 1 Sha-Chi Essence to enter [Fiend Form] for 10 seconds. While active, all attacks are unblockable and deal increased damage to Guard-Broken enemies. While in [Fiend Form], press [Power Surge] again to perform a [powerful follow-up attack] without consuming Sha-Chi Essence and exit [Fiend Form].” |
| Charged Onslaught | Weapon level 5 | “During a combo, hold [Light Attack] to charge, then unleash a rapid series of crossing slashes that infuse Fiend-Aura into the wounds, transforming [Fiend-Aura Erosion] on the enemy into [Azure Erosion], which depletes more Sha-Chi when it erupts.” |
| Corrosion Burst | Weapon level 10 | “Lv. 1: Slightly increases damage dealt by [Fiend-Aura Erosion] and its altered effects when they erupt. Lv. 2: Moderately increases damage dealt by [Fiend-Aura Erosion] and its altered effects when they erupt. Lv. 3: Greatly increases damage dealt by [Fiend-Aura Erosion] and its altered effects when they erupt.” |
| Charged Frenzy | Weapon level 15 | “During a combo, hold [Heavy Attack] to charge, then unleash a rapid series of sweeping, spinning Sha-Chi slashes that drive Fiend-Aura deep into the bone, transforming [Fiend-Aura Erosion] on the enemy into [Crimson Erosion], which deals increased damage when it erupts.” |
| Corrosive Severance | Weapon level 25 | “Press [Execute] to trigger an early eruption of [Fiend-Aura Erosion] or its altered effects on all enemies. If the eruption Guard Breaks an enemy, it greatly extends their Guard-Broken duration.” |
Arts marked with a weapon level open up as you raise Fiend Saws’ level at the forge. The forge and weapon upgrades guide explains that process.
What Fiend Saws is good for
Fiend Saws is built around Fiend Form and Fiend-Aura. Every hit builds Fiend-Aura Erosion on the enemy. Fiend Form, its Power Surge art, makes your attacks unblockable for a short window. The level arts expand on that loop. Charged Onslaught turns the erosion into Azure Erosion through a charged combo. Corrosion Burst raises the damage when the erosion erupts. Corrosive Severance lets you set off those eruptions early with Execute.
To compare it with the rest of the arsenal, the full list of weapons and Phantom Edges covers every option. The best weapons to pick up early are worth checking if you are still choosing a main weapon.
