Armor of Shadows

You touch a willing creature who isn't wearing armor and channel magic from an evil source. The shadows surrounding the target coalesce into a set of shifting jet-black interlocking plates from the waist up, spiked jet-black pauldrons, and a fine grey robe filled with spiraling, trapped shadows gifted from the evil source. The armor is infused with purple markings that give off the aura of the Queen of Air and Darkness. The helm is constituted of two black spiraling horns with a facemask that shows the horrifying visage of a tortured soul. The target's base AC becomes 13 + its Dexterity modifier. The spell ends if the target dons armor or if you dismiss the spell as an action.
