I have to say the level 1 enchanter AA: Azure Mind Crystal is disappointing.
Its takes a whopping piece of mana ( 3K it says here ) to generate a crystal that gives back 1K mana.
So the AA is not mana free and the crystal is lore so you only get one. It's not nearly as nice as the HP orbs the Necromancers get.
And its temporary, so you don't get to keep it.
