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 & Cons
- Great damage if you pair her with units that can apply Root (i.e NEO Bedivere and Tristan), but she falls off if there is no source of Root
- Same situation as units like Katrin and Cristina; used mostly for bosses and elemental advantage
