Vault of Amber

You arrange 5 small amber gems in a loose circle around any non-living materials and trace transmutation sigils above each of them. All materials within the circle are pulled into the largest of the gems and are stored there, in stasis. The gem can hold up to 500 lbs. of material and its contents do not age, weather, or rot.

You can use an action to speak a single, chosen word and release the gem's contents onto the ground. Contents are also released if the gem is dispelled.
