Perhaps the most interesting aspect of The Elder Scrolls 4: Oblivion Remastered's magic system is the opportunity to craft your own spells. This system allows players to create powerful, weird, or just plain fun combinations of magical effects once they've reached a certain point in the Mages Guild faction sidequest. Although a trend throughout much of the Elder Scrolls series, the customizable magic system was removed from Skyrim. However, it's been revived by the Oblivion remaster, and many players are diving into it again.
