With refresment being the way it is, im worshiping her with just about anything
No joke, really.
That would be fair enough... except Mystera actually offers a boon to increase your max mana. The first hit is basically free, and the second one is reasonably priced, so hitting 15 mana after your boosters is pretty easy for any
I totally agree with you on refreshment being a jaw-dropper that will get almost any character build in the door, though. I'm actually considering how I'd rank the deities from best to worst, and I can't decide whether to put Mystera or Glowing Guardian in 3rd place (Tikki Tooki and Dracul being ahead of them), and it's just
refreshment that's carrying Mystera here.
