About Ignore Damage Reduction %
This stat only works if the boss has passive skills giving him damage reduction. If not, it's useless.
Avalon, Reincarnation of Stars and Raids usually all have this passive, but always double check to make sure.
✅ Pros
Huge self buffs (ultimate skill damage, crit damage / rate, ignore damage reduction and increased damage to fire to enemies)
Great wave clear for those annoying stages with 4 parts. Every kill she also reduces the cooldown of her Ultimate, so you should be able to use it while clearing enemies and have it ready for the boss too
❌ Cons
On bosses her passive to reduce cooldown is useless since it cannot proc, can only be used on stages with waves of enemies
Outside elemental content her damage is lackluster. Most likely devs will buff her soon(tm)
