Vault
Vault is the per-player loot container in Trial Chambers, opened exactly once per account using a Trial Key.

Description
Vault blocks appear throughout Trial Chambers — underground structures introduced in Java 1.21 — and work as a per-player reward system. When a player interacts with the block while holding a Trial Key, it opens and ejects loot directly at the player's feet. A permanent internal record prevents the same account from claiming rewards a second time, while every other member of the group can still trigger their own bundle from the identical block.
An Ominous variant requires an Ominous Trial Key earned during an active Ominous Trial. Those containers draw from a better loot table and can contain the Heavy Core — the crafting ingredient for the Mace weapon. Neither form can be mined or placed by players in Survival mode; both exist only as structural dungeon furniture. Redstone signals have no interaction with either version.
