Cloaker Cloak of Cloaking

Umbral Projection: Once per long rest, the wearer can use an action to command the cloak to envelop them in shadows, granting them the ability to become incorporeal for 1 minute. While in this state, they gain resistance to all damage from non-magical attacks, can move through solid objects and creatures as if they were difficult terrain, and can't be grappled or restrained. However, they can't take any actions other than to move and their movement speed is halved.
