The Vessel become magical with an AC which equals your spell save DC and Its hit points equal the level you cast the spell plus your proficiency bonus, and it is immune to poison and psychic damage.
as an action you can magically vanish and enter the vessel, the vessel remains in the space you left. The interior of the vessel is an extra-dimensional space in the shape of a 20-foot-radius cylinder, 20 feet high, and resembles your vessel. The interior takes the shape of the inside of the vessel and have a comfortable temperature. While inside, you can hear the area around your vessel as if you were in its space. You can remain inside the vessel up 8 hours. You exit the vessel early if you use a bonus action to leave, if you die, or if the vessel is destroyed. When you exit the vessel, you appear in the unoccupied space closest to it. Any objects left in the vessel remain there until carried out, and if the vessel is destroyed, every object stored there harmlessly appears in the unoccupied spaces closest to the vessel's former space.
