You can create a temporary suspend save file to save your current progress. When you load this save file, you’ll start at the beginning of the level. If you start a new game or game mode, your learned spells, skills, dessert point count etc will still be retained. However, you’ll lose your current weapon and you’ll start off with the weapon type’s default tier. Switching to another game mode while having an existing suspend save data will also delete the suspend save data.
