There’s just a lot to keep track of:
No parries
No light attacks
No light attacks into your block
Don’t push him to sp2
Only medium if you have at least a bar of power
The only way to remove energize without buff removal is to get hit by special so try not to push him above 7
I found it best to just do the alternate sp1 ramp up: 100 prowess with 1.9 bars, get 6-7 prowess, block to get another prowess instead of refreshing, then in the next cycle sp1 while under 100 to refresh, then repeat.
Try to solo because: more time in fight, more prowess, more damage, less total time than multi shot.
I have not yet mastered the fight myself but I think I can get it in a couple of days.
Here’s my best attempt:
