Increases the DMG Reduction of Stormbreaker Spear's Martial Arts Skill by 25% after taunting a boss unit, and by 5% after taunting a non-boss unit, up to 25% in total. While the DMG Reduction is active, all damage dealt is reduced by 10%. The cooldown of Martial Arts Skill is reduced by 4 seconds. Attacking a taunted unit increases damage by 5%. While DMG Reduction is active, hitting a target recovers HP based on the Battle Will consumed by that skill (2% HP per bar of Battle Will consumed; this effect only triggers once when a single skill hits the same target multiple times, and can only trigger on up to five targets).
Applies Rodent Hunt to an enemy for 20 seconds. Upon expiring, it deals damage equal to 30% of all damage the Rats dealt to the target during its duration. Rodent Hunt cannot be delayed; hitting the same target with Bladebound Thread again immediately calculates and deals Rodent Hunt damage, and resets its duration.
The recovery rate boost from a Grace Token is increased from 30% to 50%, and the duration of rats summoned by Rodent Rampage and Charging Stance is increased to 15s, further extended to 20s by consuming all tokens when 2 Grace Tokens are present.
