I played more actually using the skill combining and it's pretty fun! The blessings and everything seem kind of OP, I got a setup that made the game super easy, but the combining is pretty interesting and neat. I like how it's balanced around mana costs more than support slots, that's a cool idea. Some kind of optional harder content would be fun, or maybe just a general rebalance. I ended up using Poison Bolts with all the +proj, homing + chain + speed, with the blessings for max MP and MP regen, and I was basically one-shotting everything from around level 35 to uhhh 100 (which was fun while watching a stream)
It's kind of strange you can just grab skills from anywhere though, it kind of seems like "build diversity" wouldn't exist since everyone should just grab every blessing, +proj/homing/chain, etc. Might make sense to lock skills behind classes... Or maybe more advanced/higher level versions of those skills on classes or class advancements or something?
Bugs:
I had a wand and buckler equipped, dragged a Short Staff on, and it let me have the buckler equipped with the 2H. I had to take it off and on a couple times for it to realize I'm not supposed to have a buckler with the 2H
It seemed like Scourge Spell wasn't aggroing enemies? (I almost remember this happening in some other ARPGs so maybe it's intentional, but very powerful)
Picking up gold from far away failed maybe half the time, probably other items too but I noticed it most with gold. Maybe I was just clicking next to it? If so a larger pickup radius or something might be nice?
