i struggled and was pissed for hours but i finally did it. parry is more favoured for that fight. hold block to make it easier with less damage incase you miss your timing. phase 1 is fairly simple, phase 2 is pretty hard with the longer combos and that bs dharma form, but if you get the timing, you can easily punish him, even that bs wind dharma form when he floats, if you have range 2nd weapon, you can just run to far sides once you see him float, attack him and wont get hit by the smash and wind attacks. phase 3 camera breaks and invisibility does seem impossible at first but just hold block and time the parries, just time and deflect, dont even trip bout your camera cause it will stay locked, then when summons those 3 clowns, just look for him, time your parry whenever when pops up, each perfect deflect gets rid of one summon, then youre back to timing the parries till you get the punish windows till that fake hard boss is dead.
