Vault Of Amber

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

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