I really enjoye doing this kind of runs, like finding skips / bugs.. stuff that are not meant to be but still exist and does help to reach some spots faster.
My build i used in this video is a Firestorm / starshot build for the boss and a evade distance / evade speed for the Running part.
All you need for the Rolling build is: Dark Fluid (concotion), Ambit ember (consumable), Rings : Anastasija's Inspiration, Deceiver's Band, Frivolous Band and Bisceted Ring ( Ring of Omen works aswell but is slightly slower)
Traits : Fitness + Wayfarer / Potency + Untouchable are completly up to you if you wanna use them. Enjoy!
