Thanks for the comment!
Sorry you didn't like the battles... I mostly focused on trying to get them balanced. I may have given the enemies a bit too much hp? I'm not super experienced with making battles and enemies.
I did start out from the default spells, but I changed the numbers and did try to change some of the animations. The blood suck in particular... Well, MZ doesn't have a bite animation (at least not that I could find), and you can't really edit the animations in MZ like you could in the older makers (there's not even a colour slider), so I couldn't make one from different animations without using effekseer, which I have no experience with. So I just found something that I thought kinda worked. I might look into finding a better animation for it online.
