If you could create one new perk what would it be and how would it work

mine is "reapers wine" basically it would work like widows wine except instead of the web grenades this would do one single 360 swipe attack with a scythe that instantly kills everything in a short range except bosses with a 10 or 5 second cool down between swipe attacks so it's not so overpowered, it would cost 4500 points and have 4 charges
