Alva's Overgrown Hut

Manipulating the very elements, you are able to create a rustic home that can fill up to a 30 foot cube, with a garden that extends an additional 10 feet all around.  You decide what this building looks like when you cast it.  This building can be placed on any surface, provided the surface is not part of a living creature.  (If placed on water, ground fills in beneath it and the garden, creating a 50x50 mini-island)  The garden consists of flora of your choice, and can provide enough food to feed up to 10 creatures daily.  Plants grown in the garden can be used as material components, but have no gold value associated with them.  Any plant plucked from the garden will magically regrow after 24 hours.  Casting Dispel Magic - if successful - will cause the garden and home to no longer be considered magical, however it will not cause them to disappear.

As long as the hut is considered magical, it and the garden have the following properties:

• Any creature in the hut or garden is immune to divination magic cast by someone other than you.
• The hut and garden are immune to necrotic damage
• Semi-sentient vines cover both the hut and garden, which obey your mental commands (no action required).  They can manipulate objects up to 10 pounds, as per the Mage Hand spell.
• Choose three creature types (such as Celestials, Fey, Fiends, Undead, Aberrations, etc.) any creature of a type you have determined who enters the hut or garden takes 4d8 necrotic or radiant damage upon doing so (you choose the damage type when you cast this spell).  They take this damage again whenever they start their turn in either the garden or hut.
  
  

If the garden and hut are no longer magical, you may cast this spell again on the same location, in order to restore their magical properties.  In addition, you may also cast this spell on the same location if the garden and hut are still magical.  Doing so will allow you to change the layout of the hut and the composition of the garden, as well as allowing you to change anything else you normally decide upon casting this spell.
