Simmumah Ur-Nokru is like most Hive wizards inDestiny 2, so players will likely now have any issues with her movement. That said, she has a few tricks up her sleeve, including sending a swarm of moths after the players which can quickly one-shot a guardian. Here’s how Simmumah can be defeated inGhosts of the Deep’s third and final encounter.
Ghosts Of The Deep: Defeat Simmumah Ur-Nokru, Lucent Necromancer
The rally banner is right at the front as players enter the arena where Oryx’s body is being resurrected by the boss. Like in Ecthar’s encounter, this encounter also has underwater sections and overground sections, though players will only need to traverse underwater to get to additional rooms in the cave system the boss encounter takes place.
Start off by destroying the ghostby Oryx’s headto begin the encounter. Somewhere in the arena,a Deepsight node will have spawned. When players interact with it, they’ll be able to spot three locations around the arena whereblack dots are hovering and a green ritual circle is highlighted on the ground. These three circles will be connected to each other with green lines.

Stand on one of these ritual circles togain the Ritual Conductor buff. A Hive knight namedVorlog, Risen In Heresy,will spawn somewhere nearby.While standing in this ritual circle, defeat him to move the boss to that specific circle.
Once Vorgol is down, two symbols should now be hovering in the air: a Hive face symbol, and a circle. Players must position themselves so that they canlook through the circle towards the Hive face symbol.This usually means moving into a different ritual circle on the arena.

Doing this reveals therequired Hive rune for that specific ritual circle—there are three in total for each phase.To find these ruins, players need to access the underwater cave doorsaround the arena and look for them. It might take some time to do this, but the encounter is not timed until players pick up a Vestige, so there’s no rush.

The cave splits off into three different rooms, where the respective Hive symbol is hovering over a group of enemies and a Lucent Lightbearer.Defeat the Lightbearer to pick up a Vestige, and return back to the central arena.
While carrying the Vestige, pick up the Deepsight buff from a node againand then head over to where therespective matching symbol is located to bank the Vestige. Once all three are banked, the ritual circles will turn into those green pools similar to the previous encounter, which will grant playersthe Piercing Light buff.Like with Ecthar, the buff allows players to destroy the boss' shield. A message stating she’s vulnerable will appear when the shield has been expended.

After one damage phase, the process restarts again.Simmumah does quite a bit of Arc damage, so players are encouraged to run double, eventriple Arc Resistance modsfor this encounter, as well as heavy ad-clear. The boss likes to teleport around the arena during the damage phase, so be ready to deal damage to her even from afar.Linear fusion riflescan be good for players who are confident in their aim—otherwise, machine gunsor rocket launchers can also be used. Be also aware of the moths that can easily sneak up and deal a lot of damage to players.
Destiny 2is available on PC, PlayStation 4, Xbox One, PlayStation 5, and Xbox Series X/S.
