Widogast's Vault of Amber is a 4th-level transmutation spell created by Caleb Widogast.


He puts out the five pieces of amber, but it takes a while [...] I cast some mumbo jumbo and the ascot goes (sucking sound). And it's gone.
Liam O'Brien describing the casting of Vault of Amber.[3]

Widogast's Vault of Amber requires one minute to cast, but can also be cast as a ritual, allowing it to be cast without expending a spell slot in exchange for increasing the casting time to eleven minutes. The spell has verbal, somatic, and material components of five amber gems worth at least 200 gold pieces.

The caster arranges the gems in a circle around up to five hundred pounds of non-living material, tracing transmutative sigils above each of them. The objects are then pulled into the largest gem, becoming stored in stasis. While stored, the material doesn't weather, age, or rot.[1] When Caleb placed Vess DeRogna's body within the Vault, it was described as: "You can just faintly see in the amber the barely visible shaded outline of a body, suspended and miniaturized in the middle of the amber."[4]

The caster can use an action to speak a command word, chosen while casting the spell, to release the stored contents of the gem onto the ground. The contents are also released if the spell was dispelled.[1]

The vault of amber was stored within Fjord's Bag of Holding to hide it and its contents from divination magic when the Tombtakers stole the Bag.[5]
