Hook is a Fire-element character who follows the Path of Destruction. She is a good early-game DPS specializing in inflicting Burn DoTs to increase her damage output. Although she is a Destruction character, only her enhanced Skill, activated after unleashing her Ultimate, can target up to three enemies for one turn. However, Hook shines more as a single-target DPS.

This is Hook’s commonly used ornament since it enhances her Skill DMG. She only needs to reach 70% Crit Rate to trigger its buff.
(2) Increases the wearer's ATK by 12%. When the wearer's SPD is equal to or higher than 135/160, the wearer deals 12%/18% more DMG.
This set improves Hook’s overall damage but requires her to reach 160 SPD to activate its highest buff. The boost is lower than Rutilent Arena, but it applies to all her attacks.
