Vacancy - Level 4 Illusion

Just writing something for one of my games, and whilst detailing one area realised that this spell isn't in 5e. So, here it is.

4th level Illusion

Sorcerer, Wizard

Casting Time: 1 Action
Range: 300ft
Area of Effect: 150ft cube
Components: V, S, M
Saving Throw: Intelligence Negates
Duration: 24 Hours

You mask a chamber or other artificial area in an illusion, making it appear empty, neglected and vacant. As with Hallucinatory Terrain any kind of interaction with the objects masked by this spell reveals the spells’ nature. Otherwise, any suspicions allow an Intelligence saving throw to see through the illusion

At Higher Levels: When cast in a slot of 8th level or higher, the duration increases to Permanent.
