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
- Incredible damage for bosses and clearing groups of enemies thanks to both her passive skills
- Can spam her active skill when she uses her Ultimate skill increasing her damage output
- Highest base critical chance that only increases even more if you are using her own card
- Can be used on any team composition without worrying about synergies
