This cloak has 5 charges and regains 1d4 charges daily at dawn.

As a reaction when a creature targets you with a melee attack (and before you know whether the attack would hit or miss), you may expend one of the cloak's charges and move 5 feet away from the attacker without provoking attacks of opportunity. When you do so, you pass through the cloak as it becomes semi-incorporeal and remains in place. The creature's attack misses.

The cloak remains in place until you move back into its space. As you pass through its form, it rematerializes back onto your person. If you re-equip the cloak on your first turn after using it to avoid an attack, you have advantage on your first melee attack that turn against the creature that triggered the reaction. If you fail to re-equip the cloak within 1 minute, it fully materializes and drops to the ground.
