WHERE IT FITS

Characters and equipment that use this material

Crescent PikePolearm★★★★

Crescent Pike

Released Sep 28, 2020Physical Normal and Charged Attack polearm with an orb or particle triggerGuide

Crescent Pike is a 4-star polearm with 43.735 base ATK and Physical DMG Bonus as its secondary stat. Picking up an Elemental Orb or Particle adds damage equal to 20% of ATK to Normal and Charged Attacks for five seconds at R1, rising to 40% at R5. Consider it for a polearm wielder who uses those attack modes and can collect an Orb or Particle before attacking; it does not provide the same effect to Skills or Bursts.

Dark Iron SwordSword★★★

Dark Iron Sword

Released Sep 28, 2020Elemental Mastery sword with a reaction-triggered ATK increaseGuide

Dark Iron Sword is a 3-star sword with 38.741 base ATK and Elemental Mastery as its secondary stat. At R1, causing one of the listed Electro-related reactions increases ATK by 20% for 12 seconds; refinements raise this to 40% at R5. Consider it when the wielder can trigger a listed reaction and benefits from Elemental Mastery as well as the conditional ATK increase. The passive is not triggered by every reaction.

Emerald OrbCatalyst★★★

Emerald Orb

Released Sep 28, 2020Three-star catalyst that offers Elemental Mastery and a conditional ATK boost after specified reactions. Consider it as a reaction-triggered, low-rarity option when its trigger list matches the wielder’s combat pattern.Guide

Emerald Orb grants Elemental Mastery and, at R1, increases ATK by 20% for 12 seconds after the wielder causes one of its listed reactions. Its passive supports a catalyst user who can reliably trigger Vaporize, Electro-Charged, Frozen, Bloom, Lunar-Charged, Lunar-Bloom, or Hydro-infused Swirl. It does not grant this buff for every possible reaction.
