Compress objects

Using your knowledge of the arcane you make a ring of gold around any non grounded object you wish who's dimensions cannot exceed 30 ft in any direction. You lay a ring of gold pieces which make a barrier that prevents objects from leaving without human interference, and you can chose to allow certain gasses to flow in or out of the barrier. (the height of this barrier is 5 feet unless you spend more fold to expand it in that dimension) After you have placed everything you want stored you present the clay statue or idol and everything within the gold ring gets transported within it, making the idol glow slightly but gain no weight. When the statue is broken any items that you previously stored in it come out in the nearest empty space. If there is no space for the items to appear on the ground the items will appear in the air and fall to the ground. If the items you put in were liquids, powders, or gasses the items contained burst out causing an effect depending on wheat was stored.

If it is a liquid it causes 1d4 bludgeoning damage per 5^3 feet of liquid in a 30 foot radius or takes half as much on a successful dexterity saving throw DC13. 

If it is a powder it explodes outwards filling the room (or a 30 foot radius if in the open) and forcing a constitution saving throw against being blinded DC12 + 1 for every 5^3 feet of powder stored.

If it is a gas the gas fills the room, or disperses if in the open, this gas can be poisonous, If a non breathable gas (such as CO2) is stored and the room is airtight, or nearly airtight anyone inside is considered to be holding their breath until additional air is let into the room.
