ΒΆ Shield of Shadowform
Armor (Shield), Rare (Requires Altunement)
While holding this shield, you have a +1 bonus to AC.
Additionally, you can use an action to transform yourself and everything you wear and carry into a shadowy cloud for 10 minutes. The effect ends if you drop to 0 hit points.
While in this form, your only method of movement is a flying speed of 10 feet. You can enter and occupy the space of another creature. When you end your turn in another creature's space, that creature takes 6d8 necrotic damage.
You have resistance to mundane damage, and you have advantage on Strength, Dexterity, and Constitution saving throws. You can pass through small holes, narrow open-ings, and even mere cracks, though you treat liquids as if they were solid surfaces. You can't fall and remain hovering in the air even when stunned or otherwise incapacitated.
While in the form of a shadowy cloud, you can't talk or manipulate objects, and any objects you were carrying or holding can't be dropped, used, or otherwise interacted with. You can't attack, cast spells, or manifest powers.
Once you use the shield to transform into a shadowy cloud, that property can't be used again until the following dusk.
