There an easy way for it if your sequence only use one vivify per cast sequence, it will be cast instantly but with the meta build you dont want only use vivify when its buffed by vivacious vivification but your really want to spam it from start to end of the fight.
Even if its hardcast its our biggest healing spell with that build.
When ever you RWK/Rem charge are on cd its should spam vivify.
If you want to use an build using ancient teaching/Master of harmony you should check the Way of the crane topic
