you could technically skip enchanted riposte and use enchanted zwerchhau/redoublement to go into the Flare/Holy combo with 45 mana, which has one extremely specific use case that I've never done before.

I have had times where the combo times out between downtime, and I've used an enchanted zwerchhau to open into Flare/Holy if I didn't have enough mana to do Riposte, like out on the open field zones
