The Vault is the fourth encounter of Last Wish and one of the raid’s most communication-heavy sections.
The fireteam must read symbols, determine which rooms require Penumbra or Antumbra, defeat Eye of Riven enemies, and use Taken Essence to cleanse the correct locations before the Vault timer expires.
There is no boss damage phase in this encounter. Success depends entirely on symbol callouts, relic movement, and accurate room assignments.
The Vault is divided into three rooms arranged around a central chamber.
Most teams refer to these rooms as Left, Middle, and Right.
Each room contains a plate and a set of symbols. Players use these symbols to determine whether each room requires Penumbra or Antumbra.
Each room displays a set of symbols.
Players must compare symbols between rooms to determine which locations need Penumbra or Antumbra.
Accurate callouts are the most important part of the encounter.
Penumbra and Antumbra are the two possible cleanse types used during the encounter.
Each room will require one of these two effects.
The team must determine the correct requirement before relic carriers begin cleansing.
Eye of Riven enemies spawn during each round.
Defeating one drops a Taken Essence relic.
The Taken Essence relic is used to cleanse the correct room.
The relic holder must know whether they have Penumbra or Antumbra and move to the room that requires it.
The encounter is timed.
If the correct cleanses are not completed before the timer expires, the fireteam wipes.
Begin by assigning one player to each room and having them read their symbols.
Compare the symbols between rooms to determine which rooms require Penumbra and which require Antumbra.
Defeat the Eye of Riven enemies when they spawn and have designated players pick up the Taken Essence relics.
Each relic holder should call out whether they have Penumbra or Antumbra.
Guide each relic holder to the correct room and cleanse the required location.
After all required cleanses are completed, the round resets.
Repeat the symbol reading, relic collection, and cleansing process until the Vault opens and the encounter is complete.
The most common cause of failure is unclear symbol callouts.
Many teams also struggle when relic holders forget whether they have Penumbra or Antumbra.
Another common issue occurs when players delay moving to their cleanse rooms, leaving too little time before the Vault timer expires.
Clear callouts, consistent symbol names, and calm relic movement make this encounter much easier.
Defeat the Might of Riven Knights before they enter the center room.
If a Knight reaches the center area before being killed, the challenge fails.
Assign players to watch each side room and call out Knight spawns immediately.
As soon as a Might of Riven appears, focus it down before it can move into the center chamber.
Because the Vault encounter already requires strong communication, the challenge mostly adds pressure to enemy control.
Players should prioritize Knights over general add clear whenever they appear.
Most failures occur when a Knight spawns and moves unnoticed toward the center.
Another common issue is players becoming too focused on symbol callouts or relic movement and ignoring enemy spawns.
Keep one player responsible for calling out Knights in each room, and eliminate them as soon as they appear.
