Piercing Damage

Piercing Damage (also known as Mitigation Pierce) is an effect found on some units UBB that deal more damage to enemies with Damage Mitigation buff active.

Interactions with Mitigation effects
Mitigation Pierce can only pierce Damage Mitigation, reducing its overall effectiveness. It is not usable against Elemental Mitigation and Guard Mitigation. Additionally, it cannot pierce mitigation passively found in Leader Skill and Extra Skill effects.
