Oh hey. DPS shotgun. Like every other DPS shotgun, she has the issue of “when would this even be relevant?” So, I’m not going to focus on that.
The main eye-catching bit of her skill is the instant kill shot once she hits 100 stacks. While useful, it only happens once per battle, so you can’t rely on it. Her real strength comes from her having perfect accuracy, higher knockback chance, and no need to reload. This can make her an absolute monster when knockback is desired.
The problem with this comes with the constraints that you need to follow to really get her going. First, you need another shotgun with her, which isn’t terribly difficult. Next, you need to have her hit 100 stacks. You get one per hit on an enemy, which may sound like a lot, but it isn’t. This takes into account dummy links, as well as the fact that shotguns hit multiple enemies, so you can get up to 25 stacks per shot. (Assuming you’re using bird shot, which you should be using) It’s entirely feasible to get 100 stacks in one of her mags. However, this can be an issue in battles with lower enemy count, which will hamper her stack gains.
