WHERE IT FITS

Characters and equipment that use this material

Portable Power SawClaymore★★★★

Portable Power Saw

Released Sep 27, 2023Healing-triggered Elemental Mastery and Energy claymoreGuide

Portable Power Saw is a four-star claymore with an HP secondary stat. Healing the wielder or having the wielder heal grants symbols; using an Elemental Skill or Burst consumes them for Elemental Mastery and Energy restoration. Consider it when healing can build symbols and the wielder can time a Skill or Burst to use them, especially if the wielder benefits from Elemental Mastery.

Tidal ShadowClaymore★★★★

Tidal Shadow

Released Aug 16, 2023A claymore whose ATK secondary stat and healing-triggered passive suit a damage dealer who can receive healing during combat.Guide

Tidal Shadow is a 4-star claymore with an ATK secondary stat. After its wielder is healed, it gains an ATK increase for 8 seconds; because this can trigger off-field, it can also benefit a character who swaps out after being healed. Consider it when your setup provides reliable healing and the wielder’s damage scales with ATK.

Tome of the Eternal FlowCatalyst★★★★★

Tome of the Eternal Flow

Released Sep 27, 2023Catalyst for Charged Attack damage with an HP bonus and Energy return tied to HP changes. Consider it for a wielder whose current HP can change often enough to build and maintain its stacks.Guide

Tome of the Eternal Flow rewards changes in the wielder's current HP. Each increase or decrease can build a short-lived Charged Attack DMG stack, and reaching or refreshing the third stack restores Energy on a separate cooldown.

VerdictClaymore★★★★★

Verdict

Released Dec 20, 2023Claymore that boosts ATK and Elemental Skill damage after Crystallize shards or Lunar-Crystallize. Consider it when the party can generate those triggers and the wielder deals meaningful Skill damage.Guide

Verdict combines a CRIT Rate secondary stat and ATK increase with a Seal mechanic that boosts Elemental Skill damage. Seals come from party members obtaining Elemental Shards from Crystallize or triggering Lunar-Crystallize, and are spent shortly after the wielder's Skill deals damage.
