Ominous Trial Key
Ominous Trial Key drops from spawners during Ominous Trials and opens the rarer Ominous Vaults in Trial Chambers.
Description
Its sole purpose is opening Ominous Vaults — the reinforced loot containers found in Trial Chambers that require exactly this key. Those containers draw from a better loot pool than standard Vaults and are the only reliable source of the Heavy Core, the crafting component for the Mace weapon. The Bad Omen effect is applied by drinking an Ominous Bottle or by raiding a pillager outpost, so collecting these keys requires deliberate preparation. Players who want the Mace without grinding standard runs should activate Bad Omen before entering to maximize the Ominous drop rate per session.
