My skill rotation:
1) Battle opener:
Nemesis-quick aura(cons) -Conversion(save) -Enchant grip(swift) -rush(cons)
punch to stack asura, manual e grip to add stack to 2 or 3
2) Nemesis release-E burst:
slide-combination(reflect)-Eslash(save) -conversion(cons)-dual bringer(cons) -flasblink(cons) - e burst(smite)-rush(cons)
Eslash on conversion mode is flipped to physical so it might get evaded, but e burst on no conversion mode is magic so you're sure to get weaken
3) Reunion-nemesis link:
Floating kick-Terrablast(save) -E Slash(bloodsuck) -conversion (cons) -flashblink(cons) -Union sword(smite) -e grip(cons) -nemesis(cons) -rush(cons)
Reunion release+ nemesis link. remove e grip if you need a shorter duration combo and stack with manual e grip instead. I just put it in to simplify the rotation. Then repeat the step 2
you can abstract at certain points in your combo if needed so the train combo isn't actually that long to be a problem. Siphon barrier and e grip are on the shorcut to be used as needed.
