Spell Saver

You are incredibly powerful with your magic and can occasionally manage to save a spell. Twice per long rest you can attempt to conserve a spell slot. In order to do so you must role a d100 and add your spellcasting modifier to the roll. The level of the spell determines the success rate as shown in the table below. If the spell slot is not saved, the player takes 1d4 + (Spell Level * 2) Psychic Damage.
