Ominous Trial Key

An ominous trial key opens one ominous vault and is earned through the harder trial spawner encounter.

What is Ominous Trial Key?

The ominous trial key is the upgraded counterpart to the regular trial key. It unlocks an ominous vault in a trial chamber. The vault ejects a set of rewards for that opening, with a heavy core among the possible outcomes.

Why players overlook it

A regular chamber can produce a collection of normal keys before a player learns the upgraded route. The two keys look related and share a name, but spending time at an ordinary vault does not help if the loot you want is in an ominous one.

How to get it

  • Drink an ominous bottle and get detected by an eligible trial spawner while the relevant omen applies.
  • Complete the ominous encounter and check its reward. A key is a possible outcome rather than an item guaranteed by every spawner.

What is it used for?

  • Use an ominous trial key on an ominous vault you have not opened as that player.
  • Keep normal keys separate, since the two items have different destinations.

When it comes in handy

Mark opened vaults while exploring a large chamber. This saves a trip back through corridors when you have earned another key and need a vault you can still use.

Limitations

A key is consumed when you use it. The key itself does not guarantee a heavy core, and a vault already opened by the same player cannot keep providing repeat loot for that player.

Editorial recommendation

Is it worth using?

Keep each key until you have an eligible vault, even if you are done with a chamber for now. They are the bottleneck between the ominous fight and its loot.

Alternatives

Use a regular trial key for an ordinary vault. Take extra supplies and another bottle if you need more opportunities to earn ominous keys.
