Yep, this guide from Reddit helped me out a lot with understanding the class

Basic rotation is just spark -> dualcast verthunder to build up black mana or veraera to build up white mana -> Spark/Verfire/Verstone depending on if you got a proc -> dualcast verthunder or veraero to build up the opposite mana you received before
repeat until both bars are at 80+, then do the corps-a-corps -> enchanted riposte -> enchanted zerchhau -> enchanted dedoublement -> displacement -> cast spark and start rebuilding mana pool
I'm only 50 so that's basically my entire routine, the 50-70 skills are basically buffs/things to skip to melee phase earlier, etc. But that building up mana -> switching to melee -> building up mana is the core loop of the class
