Arcane Repository

Cast this spell to create a Magical storage container to hold your loot. This spell can only be casted on an already existing  storage container, that is capable of containing and covering loot, (ex. a drawer that can be shut or a bag that can be closed.) the original contents of the container are transported elsewhere in a safe, unreachable location.

You can fill this container with any items or creatures that can fit. When the spell ends the items swap places with the original contents of the container. From now on Any time you cast Arcane Repository on another storage container, you can gain access to your arcane Stash. If the container you cast the spell on is different than a previous container the items will automatically place themselves in the container based on the casters personality. but all the items will still be there so long as there is physical room. 

This Spell Scales with your Player Level.

Beginning at level 5 you can cast Arcane Repository on Any Small Container. (Equal or less than 2 ft.² Ex. Drawer, BurlapSack, Cabinet.) 

At 8th Level you can cast Arcane Repository on any Medium container. (Equal to or less than 6 ft.² Ex. Chest, Crate, Safe) Also at 8th level you can choose whether the container becomes locked or unlocked when you cast arcane repository on it. (This will not unlock a locked container)

Starting at 10th Level, you can cast arcane repository on a small stone or object.  This enchanted object stays enchanted for 14 days. The stone has the holders AC. 
Squeezing the stone alerts the caster, even if they are sleeping. 

The holder may use the stone to cast Arcane repository once per charge before it is destroyed, To access the CASTERS Arcane stash. 

You May cast arcane repository but it will consume any remaining charges, destroying the stone.
every level after character level 10, the charges increase by 1, casting this spell at character level 10 yields 1 charge

At 12th Level you can cast Arcane Repository on a Large container. (Equal to or less than 20 ft.² Ex. large wardrobe, closet, coffin.) Also at 12th level creatures can breath in a very large container for 12 hours even after the spell is ended and the container is returned to its pocket dimension.

for ever level you gain after 12 the amount of hours a creature can breath in your arcane stash is doubled.

At 15th level you can cast Arcane Repository on Very Large Containers (equal to or less than 65 ft.² Ex. A covered wagon, A small room like a bathroom, large shipping containers. Bag of holding.) 

If the container Arcane Repository is casted on cannot hold all of the items or creatures that were placed in any previously enchanted container, only those items that could fit in the container will appear. Those items are selected randomly unless you specify when you cast the spell what items you would like to be included.

If an item the caster request cannot appear. The DM can say so, and the spell may not be casted if the caster chooses so.

when returning to the pocket dimension, the container will continue to hold it last known physical description. While in the container in its pocket dimension, it can be changed by the caster at will up to the largest container size. And those items that cannot fit will exist outside of the container, but will be returned when the container is large enough.

The containers contents are attached to the caster themselves. If the castor loses the ability to cast arcane repository, the items can still be accessed via a scroll of Arcane Repository (good luck finding that anywhere but Solas) the arcane stash only disappears if the caster is completely dead. If Resurrected, the items return.

This spell can be casted offensively in combat On an enemies bag, for example, in that case the owner of the container can make a Wisdom Saving throw to avoid the effect. 

The “void” in which items are returned is in the sky above a massive ocean of lava on located on Solva.
