Off-tank DPS that hates Elite units and provides various benefits. Her damage increase isn't stellar, but she has enough rider effects that you can probably find some use for her. Like C-MS, she can equip AP rounds. YMMV with regard to how useful that is.

On one hand, her passive debuffs the enemy quite nicely. On the other hand, her stats kinda suck, and her active is basically a glorified stun, and yes, anything immune to stun is immune to her, too.

Since EN lacks the chip, she actually has good DPS. Once EN gets the chip, her DPS is kinda meh.
