This spell forms a shimmering, radiant field around you like a suit of armor. As long as you maintain this spell, each time a weapon attack would hit you, as a reaction you can expend a 1st-level spell slot to either gain damage reduction or increase your AC by +1. If the increased AC would cause the attack to miss, then the attack misses instead. You must declare your choice before the GM announces the damage from this attack.

Damage Reduction. For each level of the spell slot you expend, bludgeoning, piercing, and slashing damage you take from nonmagical weapons is reduced by 3 points.

At higher levels.For each level of the spell slot you expend, your AC increases by +1 against that attack.
