You create an alternate dimensional dwelling within casting distance and maintain it until the end of the spell’s duration. The dwelling’s only glowing entrance is 5 feet wide and 10 feet high, and its location is specified by you. As long as the portal remains open, you and any creature you specify when you cast the spell can enter the otherworldly dwelling.

Mordenkainen’s Magnificent Mansion 5e

Level: 7th

Classes: Wizard, Bard

Casting Time: 1 minute

Range: 300 feet

Components: V, S, M

Duration: 24 hours

You can open and close the portal no more than 30 feet from the portal. When the portal is closed, it is invisible. Inside the entrance is a magnificent hall that connects many rooms. The air inside is clean, fresh and warm.

You are free to create your own room configuration, but the total volume should not exceed 50 cubes 10 feet long. The room is furnished and decorated to your liking, and is stocked with enough ingredients to prepare a nine-course meal for 100 people.

A group of 100 translucent servants will entertain anyone who enters the room. You decide how you want your servants to look and dress, and they will obey your orders completely. Each servant can to perform a normal human level job, but they cannot attack or perform any actions that directly harm other creatures.

Thus servants can perform tasks such as fetching items, cleaning, repairing, folding laundry, building fires, serving food, pouring wine, and so on. A servant can go anywhere in a mansion, but cannot open the mansion inside. Furniture and other items created by the spell dissipate into smoke if they are removed from the mansion.

When the spell terminates, any creature in that alternate dimension is removed from the space and appears in the open space closest to the entrance.
