Bare Knuckle EO Soulfist trixion (read description)
Suggest to run ot1 lb2 if you're full level 8 cd gems , and lb3 if you're full 10s cd , ot1 with full 10s is higher ceiling but it's probably not viable for real raid scenarios.
25 swiftness + swift bracelet means you're hitting at least 21.5% evo from supersonic breakthrough with atk speed feast and peyto wine , so it's already better than standing striker , in raids you can also collect wind orbs and support atk speed will increase the evo even more , in alternative you can buy an atk speed bracelet that would definitely cap it and turn the atk speed bracelet into a 2.5% evo damage line which is not completely worthless I guess.
you can invest more swiftness if you prefer , I think the extra cd doesn't have that much value though , compared to the extra crit you're sitting at 90% crit rate currently without back attack , if you have a crit synergy I would drop natural body to 2 and go EE3
in alternative to force orb you can run crippling barrier for push immunity at the cost of worse stagger , talking about stagger those are the stagger values of your skills without any runes:
pulverizing palm 76
bolting crash 269
celestial palm 240
merciless pummel 444
lightning palm 76
shadowbreaker 149
flash step x3 225
force orb 321
crippling barrier 37
