Shadow Ward

This eerily still cloak seems to absorb some of the light that touches it. While wearing this cloak, you have advantage on Dexterity (Stealth) checks. In addition, the cloak has 3 charges and regains 1d3 expended charges daily at dusk. When you’re hit by an attack, you can use a reaction to expend 1 of the cloak’s charges to halve the damage you take from the attack and teleport in a plume of black smoke to an unoccupied space you can see within 30 feet of you.
