WHERE IT FITS

Characters and equipment that use this material

Bow★★★★

Chain Breaker

Released Aug 28, 2024Party-composition ATK and Elemental Mastery bowGuide

Chain Breaker is a four-star bow with an ATK secondary stat. Its passive counts party members who are from Natlan or have a different Elemental Type from the wielder; each counted character adds ATK, and three or more counted characters also grant Elemental Mastery. Consider it when the party naturally meets those conditions and the wielder benefits from ATK, with the extra Mastery relevant to their damage.

Catalyst★★★★★

Crane's Echoing Call

Released Jan 31, 2024Plunging Attack support catalyst with off-field Energy returnGuide

Crane's Echoing Call is a 5-star catalyst with 49.138 base ATK and ATK as its secondary stat. After the wielder hits an opponent with a Plunging Attack, nearby party members gain increased Plunging Attack DMG for 20 seconds. Their Plunging Attack hits can also restore Energy to the wielder, even while the wielder is off-field. Consider it when the party actually uses Plunging Attacks and the wielder can activate the buff; its team value depends on that specific attack mode.

Polearm★★★★

Dialogues of the Desert Sages

Released Mar 14, 2024Healing-triggered Energy support polearmGuide

Dialogues of the Desert Sages is a 4-star polearm with HP as its secondary stat. Consider it for a polearm wielder who heals: each healing trigger restores Energy, including when the wielder is off field. Its value is support and burst uptime rather than a direct damage bonus.

Bow★★★★★

Silvershower Heartstrings

Released Jun 25, 2024HP-focused bow with a three-condition stack mechanicGuide

Silvershower Heartstrings is a five-star bow with an HP secondary stat. Its Remedy stacks increase Max HP, and reaching three stacks also grants Elemental Burst CRIT Rate. Consider it for a bow wielder whose actions can meet multiple stack conditions and whose Burst benefits from CRIT Rate.
