So, [Higasa] is a ok gun, this is the best i could get and it does its job alright. its fun to use but not practical for late game but its still useable in sp. Just swap out [Serration] for the [Higasa] [Serration] mod as its not a thing in overframe, aside from that using it along with [Koumei] when she has the primary stat booster passive on, this gun does pretty nicely.
