Vhaeraun's Nightshield

You protect yourself with a cloaklike aura of black energy. This aura has two effects. First, it absorbs 5 points of magic missile damage, similar to a brooch of shielding. Second, it provides a +1 resistance bonus on saving throws.

If cast as a 3rd level spell slot, it absorbs 10 damage and increases to +2  the resistance bonus to saving throws.

If cast as a 5th level spell slot, it absorbs 15 damage and increases to +3  the resistance bonus to saving throws.

The spell ends if it absorbs its full capacity of magic missile damage.
