Everything playable now is indicative of early game difficulty more than anything. As I start to work on the next couple of areas, fights are gonna start to get more complicated and more challenging. I'll also introduce more customizable difficulty options later on down the line.
As far as magic, I'm hoping that once bosses start to have more attacks of their own, things will naturally balance out a bit. One thing I have planned as a potential adjustment for spells, though, is making them require stamina so they'd be a bit harder to spam. Thank you for the feedback!
