Specific Damage Mitigation

Specific Damage Mitigation (also known as Specific Damage Reduction) is an effect that reduces specific types of damage taken, including Unit Skills, Damage over Time, Normal Attacks, and Enemy Skills. It is one of the variants of Damage Mitigation.
This mitigation can also appear with negative values, causing affected units to take more damage. This is most notable on Ancient Calamity Arumat's Extra Skill.
The only units that have these effects are Spirit Conjurer Astrid on Leader Skill and Ancient Calamity Arumat, Zedus the Great, and Orochi Iori on Extra Skill.
==In Arena/Colosseum==
Currently, there are no units that reduce damage taken from Unit Skills. As such, Specific Damage Mitigation from currently released units does not work in Arena game modes.
