Shadow Armor

1st-level abjuration (shadow)

Casting Time: 1 reaction, which you take when you are targeted by an attack but before the roll is made
Range: Self
Components: V, S
Duration: Instantaneous

You can siphon energy from the plane of shadow to protect yourself from an immediate threat. As a reaction, you pull shadows around yourself to distort reality. The attack against you is made with disadvantage, and you have resistance to radiant damage until the start of your next turn.
