Really stood out against the rest of the game which wasn't bad by any stretch just repetitive. There are some serious combat challenges too. Just make sure you play on hard. It really needed one difficulty higher tbh.
Patient Gamers
A gaming community free from the hype and oversaturation of current releases, catering to gamers who wait at least 12 months after release to play a game.

Heretic and Lichdom: Battlemage
Theoretically, Immortals of Aveum could be good for this. It’s basically a shooter, but with spellcasting for the shots.
Play Skyrim with ordinator mod that adds more spells.
