Recently I wanted to play a magical combat game and Hogwarts legacy seemed to be mostly what I was looking for so I ethically acquired a copy. Unfortunately even with DRM removed it runs very poorly on my laptop.
Looking through steam games tagged magic, I didn't manage to find something similar. Most of the games I saw were either top-down/side-scroll (I'm looking for FPS/TPS) or had magic systems simpler than in Skyrim (I want magical combat to be the main focus).
Two Worlds 2 had a very interesting idea for a magic system where you find cards and slot them to create and modify spells. It's pretty jank but maybe worth a look. The game also had one of the most interesting multiplayer setups for open world rpgs I've ever seen.
