She's capable of good damage, that's about it. She's very good against enemies with a rage bar, as she deals extra large amounts of damage to enemy when in raging state, and her assist also gives her 15% more ATK when enemy is in rage... that, AND she has 5T crit chance with just a 7T CD.
Burst gauge up 15% with her offense ability, so she is pretty much a rage/burst nuker... better than SRs in main team. I believe she gets a future buff? but i'm not sure.
But it is worth using her in your main team alongside Sol/Micheal and Diana. GZ on finding her, btw
