People had given some good info and tips already so I'm just gonna say a few things I like to say to new Scholars:

Don't think on Lustrate being a emergency heal, it can work godly as one of the best emergency heals of the game but SCH actually depends on constant Lustrate to keep healing without using too much mana. I recommend you learning about your fairies, read their skills and use fairy on obey so you can get used about using their cd skills. Don't get stuck on only one fairy, use both so you can feel how powerfull they both are. Once you get used to them you'll start of casting manual Embraces without even noticing. And last but not least, when aetherflow comes out of cd just burn your stacks whatever you like but thats a good opportunity to Energy Drain and get a bit more mana back.
