So as I am understanding it based on 10 levels of Arcanist....
Aetherflow is both a spell and a buff?
I cast Aetherflow, and the spell gives me a one-time infusion of Magic Points, and then gives me the "Aetherflow State" which is kinda like a stance?
and the Aetherflow buff lasts until I Energy Drain once, and then Energy Drain consumes it?
So I should be casting Aetherflow repeatedly, all the time, instead of only when I am low on MP?
