Dvaleer's Living Sanctuary

An immobile wall of plants of a type you choose grow around you and remains stationary for the duration. When you create the wall you can choose its shape to be a  10 ft. tall dome, cylinder, or square but its area cannot exceed 200 square feet. The wall remains until it is reduced to 0 hit points at which point any remaining plants wither and disappear. The wall has an AC equal to your spell save DC and hit points equal to your hit points. It is immune to psychic damage and vulnerable to fire damage.

The atmosphere inside the space is comfortable and dry, regardless of the weather outside. The entire floor within the wall becomes a comfortable bed of plants of your choice. While within the wall, you can command the interior to become dimly lit or dark. The wall is opaque from the outside, but sound can pass through unhindered. While within the wall, you can spread the plants apart so you can see through the wall. You have 3/4 cover while in the wall but creature outside while you are within the wall also have 3/4 cover.

Nine creatures of Medium size or smaller can fit inside the wall with you. The spell fails if its area includes a larger creature or more than nine creatures. Creatures and objects within the wall when you cast this spell can, as a bonus action, make the plants form a doorway or hole in the wall that closes at the end of their turn. All other creatures and objects cannot pass through while the wall exists. Spells and other magical effects can't be cast through the wall, but area of effect spells can enter it.
