I dont know if this could be any buggier than this.
Opening Strike – barely ever works. Boon icon is present but when I shoot from further distance than 300-500 it does not apply vulnerability – ever. If I take shoot from less than 300 then sometimes it works, sometimes it doesnt.
Alpha Training – When boon icon present, sometimes works, sometimes doesnt. Same issue as above but even in melee range it doesnt work most of the time.
