@kuttoe is it any way to get rid of the grim bargain spell from you're sim? if not can you make one, if a sim doesn't use the Untamed magic for a couple of days or magic at all it should slowly go away
Do you mean unlearn the spell or get rid of the effects? There's no way to unlearn the spell other than remove the mod. The effects of the spell up to level 4 will completely go away after about a day per level if you stop casting Grim Bargain. If you reach level 5, the effects are permanent, and will not go away unless you use cheats to remove the trait or uninstall the mod.
