Dimensional Storage

Summary
Dimensional Storage is the ability to store anything in a fold of dimension/space and re-materialize at will.

The user can put items/beings into a separate dimension for safe keeping and can summon them back with relative ease.

There are various different methods of "Pocketing": have holes or areas on the body that "suck" objects in. "Bag of Tricks" or "Magic satchel" to hold infinite amounts of objects inside. "Floating" portal or simply reach behind/in anything and pull out the wanted item. Even "Trade In/Out" for any items that they have right now and the items that they want from their dimension, ex. trading a pistol for a shotgun or one's clothing for a new tier set.

Limitations

 * Heavier objects may strain the user.
 * The entry-point may place limits for the size of the stored object.
