Emberwell

Released Aug 12, 2026Reaction-oriented four-star sword with Elemental Mastery and conditional ATK or Stellar Glimmer reaction damage buffs. Consider it when the wielder can trigger reactions regularly and benefits from those stats.Guide

Emberwell rewards reaction triggers, including off-field triggers. At R1, triggering an Elemental Reaction raises the wielder’s ATK by 16% for 12 seconds; triggering Stellar Glimmer also raises that reaction’s damage by 16% for 12 seconds. Both effects can trigger off-field. Its Elemental Mastery secondary stat supports reaction-focused use, while the ATK effect fits characters whose damage scales with ATK.
