The New Divinity boss fight

I find the boss fight quite frustrating with the "non-cheese" method and felt it's better just to chain smash and windmill. Windmill will reset the boss AI and cancel most of its skills, most importantly the debuff that don't let you use the shield skill to defend against its 1hko move. Even after getting the nascent divinity it's still just to cancel transformation and go back chain smash windmill.
