Bag of Personal Enviornements

Inside of this small pouch, the player (or user) can reach in and grab a tile inside.
There are several different tiles that can be inside the bag:
1 - Desert
2 - Jungle
3 - Grassy Planes
4 - Rocky
5 - Water
6 - Snow
7 - Fire Plane
The DM can specifically choose up to 6 of these tiles in whatever pattern they desire the player to have (ex. 3 desert, 1 water, 2 rocky) but they do not need to give 6 tiles.
Once a tile is used it cannot be reobtained.
Once a tile is chosen, the player throws it onto the ground (range determined by their Dex modifier (x) 10ft) and it forms a 30ft x 30ft x 30ft area with a perpetual terrain determined by the selected terrain tile (ex. a player could throw a snow tile in a dessert and it will not melt, it will have the attributes of a snowy terrain without any interference from the surrounding original terrain).
The terrain will not dissappear until either the one who placed the tile speaks its command or until 1d8 x 1d4 years or until it is forcibly destroyed.
