Divinnus' Portable Treehouse

A 20-foot treehouse springs into existence in front of you for the duration. The treehouse accurately resembles a tree you can see in the immediate vicinity; or the tree that your material component came from. The treehouse has a single row of 10-foot branches 10 feet up the trunk, wrapped tightly with vines serving as a floor. And another set of branches 20 feet up arching down in a 10-foot dome meeting the first set of branches. The treehouse's branches are covered in a layer of thick leaves that obscures the inside. A single vine hangs down from the top of the treehouse and falls through an opening in the floor allowing creatures the climb inside, You can open and close the gap as well as raise or lower the vine at will. The inside is lined with bioluminescent plants which you can command to become dimly lit (any color you choose) or dark. The spell ends when you leave its area. Nine creatures of Medium size or smaller can fit inside the tree with you. The spell fails if its area includes a larger creature or more than nine creatures. Creatures and objects within the dome when you cast this spell can move through it freely. To discern that the treehouse is a ruse, a creature can use its action to inspect its appearance and must succeed on an Intelligence (Nature) check against your spell save DC. The atmosphere inside the space is comfortable and dry, regardless of the weather outside, until the treehouse is hit with an attack. The treehouse has an AC of xx and HP of xx.
