The core of fire teams with the most insane single target damage in the game even though she's a standard doll. She can do some decent AoE with her skill 2 + fixed key 4, but I don't recommend using it as the skill is very awkward.
Her movement range is also quite low so don't bring her in big extraction maps. Her ultimate stacks can go down very fast and hard to maintain so you need to micro manage a lot to get max damage with her team.
Worth going for high dupes as the higher you go the crazier she gets, but definitely not necessary (v3 is good enough imo).
V3 is the breakpoint you want, after that is just how much more damage you want her to do because from v3 to v6 her damage will keep going up.
This key not only boosts her damage but also allows her to use the fire boost set and utilize the burn damage buffs from Vector and Centaureissi's expansion keys. A very nice key to get for fire teams.
