I will give you my simple opener

I am on my phone now so the skill name might not be correct wording so I am sorry

Kasha combo >> Hagakure
Gekko combo >> Kaiten >> banana >> miko >> ice >> Kasha >> gekko >> kaiten Midare >> guren

As for the follow up always go for 3 sen kaiten Midare and never ever use Hagakure for guren it's a dps lost and always keep the DoT up and spend you ki and don't let your guren unused for too long and your dps will be 4.4k at i314 fully meld
