Dvaleer's Magnificent Treehouse

You touch a tree, plant, or the ground and create a door to an extradimensional dwelling that lasts for the duration. The entrance shimmers faintly and is 5 feet wide and 10 feet tall or fills the entire plant. You and any creature you designate when you cast the spell can enter the extradimensional dwelling as long as the portal remains open. You can open or close the portal if you are within 30 feet of it. While closed, the portal is invisible.

Beyond the portal is a magnificent foyer with numerous chambers beyond. The atmosphere is clean, fresh, and warm.

You can create any floor plan you like, but the space can't exceed 50 cubes, each cube being 10 feet on each side. The place is furnished and decorated as you choose. Everything within the treehouse can appear as anything, but, upon closer inspection, everything is made of wood. Certain spell effects, like levitation, can be used in the treehouse if the DM allows it. You can change the layout of the treehouse or anything inside it while the spell remains. It contains sufficient food to serve a nine-course banquet for up to 100 people. A staff of up to 100 servants attends all who enter. You decide the visual appearance of these servants and their attire. They are completely obedient to your orders. Each servant can perform any task a normal human servant could perform, but they can't attack or take any action that would directly harm another creature. Thus the servants can fetch things, clean, mend, fold clothes, light fires, serve food, pour wine, and so on. The servants can go anywhere in the dwelling you designate but can't leave it. Furnishings and other objects created by this spell dissipate into flowers then into smoke if removed from the mansion. When the spell ends, any creatures inside the extradimensional space are expelled into the open spaces nearest to the entrance.

The treehouse becomes permanent if the spell is cast with the same layout every day for a year. While the treehouse is permanent the layout and contents cannot be changed unless the spell is cast on it. The changed form then remains permanent.

If this spell is cast at 8th level the food gives the effects of Heroes' Feast. If cast at 9th level, the food gives the effect of Heroes' Feast as well as giving immunity to the charmed condition, double the max health boost, and gives the one effect of Greater Restoration of the spellcaster's choice.
