The Investigation is the second mission in The Witch Queen campaign for Destiny 2. It serves as an introduction to the Throne World zone, the second type of Lucent Lightbearer you'll fight throughout the campaign, and it introduces the Deepsight mechanic.
While this mission doesn't seem to have a Master variant as of writing, the Legendary version of this mission can be difficult if you're attempting this solo or flawlessly. This guide will go over the best subclass and weapons to bring, and we'll break down the best way to complete each encounter. And if you haven't started the Legendary campaign yet, give our walkthrough of The Arrival mission a look.

Investigate Savathun's Throne World
You'll start the mission in Savathun's Throne World, just outside of her cathedral. Make your way back to the entrance of the cathedral. A few Hive enemies will be guarding the area, so clear them out. A rather tanky Hive Knight will charge at you when you arrive. Use your Special weapon to kill them.
Shortly after killing the initial group of Hive a Lucent Lightbearer will spawn to the left of the cathedral entrance. It's the same enemy type you fought in the previous mission. Avoid its shield throw attacks whenever it enters its Super, and use your Heavy weapon to make short work of this miniboss. Stasis can also stunlock the Lightbearer, freezing it long enough to force the Knight out of its Super. Remember to crush its Ghost once you've killed the Knight.
It looks like Savathun's cathedral is locked, so you'll need to find another way through the Throne World. Backtrack to where you start, and you should see a green forcefield blocking a pathway. Two Hive Knights will be protecting this field, both of which have Arc shields. Killing both of them will reveal a Deepsight orb near the back of the courtyard. Interact with it. Your Deepsight vision will reveal some nearby platforms, leading you to a nearby building.
Deepsight is a 30-second buff that alters the environment around you. While active, new platforms will be created, statues will change, and entire walls might be lifted. Use these Deepsight orbs whenever possible to find the path forward.
Follow The Signal
You should now be in a dark maze inhabited by a few Hive Thrall. For the first part, you'll want to keep heading right whenever possible. You'll eventually reach a cavernous room with a Deepsight orb near the bottom. Use the orb to find your way forward.
Continue exploring until you reach a T-shaped corridor that seems to be a dead end. You'll want to head right. Defeat the Thrall and Knight residing in the room, then activate the Deepsight orb in the corner. Backtrack to the corridor and go in the opposite direction. The Deepsight will create platforms you can climb on to reach the next room.
That next room contains a small group of Cursed Thralls and a Hive Knight. This room is quite dangerous if you're going for flawless, so play on the defensive. Use Stasis or any AoE weapons to quickly kill the Thrall, then eliminate the Knight. A short run will lead you outside.
Outside of the maze, you'll need to fight across the Florescent Canal to reach this mysterious contact. Multiple Taken Knights are present here, so use your Super. Melt them as fast as you can, then push forward. A Hive Ogre will be guarding the path, nothing a Heavy weapon can't deal with. At this point, we recommend hopping on your Sparrow to bypass the rest of the enemies.
The gate will be guarded by yet another group of Hive. Kill the Knight as soon as possible, then focus on the Acolytes. When finished, grab any nearby ammo and reload your weapons. It's time to start an encounter.
Rendezvous With The Contact
| Encounter Breakdown | |
|---|---|
| Objective | Hold the area until the gate opens. |
| Notable Enemies | Hive Knights |
| Shields | Arc |
A nearby gate is preventing you from further exploring Savathun's Throne World. You'll need to defend a nearby Hive pillar to lower the gate. Stand on the pillar when you're ready.
Enemies will begin to swarm the pillar from across the gate. Most will spawn near the patch of land the pillar is on, although some will spawn on the road towards the end of the encounter. Your main threat is the Hive Knight enemies that periodically spawn, usually accompanied by a Hive Moth. Stasis, Sunspots, and any persisting AoE effects work wonders during this part. Should you get swarmed, back off the plate and take the enemies out from a distance; standing on the plate will spawn more enemies. Once you've fully captured the plate, hop on your Sparrow and book it to the newly-opened gate. Follow the path to the next encounter.
Escape The Fortress
| Encounter Breakdown | |
|---|---|
| Objective | Defeat the Hive and Scorn guarding the exit. |
| Notable Enemies | Barrier Guard Knights, Scorn Abominations, Lucent Lightbearer (Wizard) |
| Shields | Arc |
This is the hardest encounter in this mission. You'll spawn just outside of a Hive vs. Scorn battle. Interrupt the fight with a well-placed grenade or AoE weapon. Focus on the Abomination and the Barrier Guard Knight. Clean up the nearby enemies when done.
Killing these enemies will spawn three Abominations and Barrier Guard Knights, one on each side of the arena. Focus on clearing out the left, middle, or right side at a time; trying to clear all three at once will get you killed. When clearing a particular side, try your best to stick to cover, avoiding any Taken Thrall closing on your location. This is where Witherhoard, Stasis, or Sunspots come in handy. Many of the enemies spawn in predictable areas on the map (usually near the middle path), so a good AoE weapon can one-shot a pack of enemies. Clear out the adds on a given side, then kill the Abomination and Guard Knight. Feel free to use your Heavy on them.
When all three sides are clear, a Lucent Lightbearer will spawn at the middle road. This is effectively a Stormcaller Warlock disguised as a Hive Wizard, utilizing Stormtrance and Lightning Grenades to flush you out of cover. While deadly, the Lightbearer is quite passive and won't push your location if you keep your distance. Your best bet is to damage the Lightbearer from afar, preferably with your Heavy weapon. The Wizard will deploy a Healing Rift if it takes enough damage, so be quick.
Damaging her enough will spawn two Barrier Guard Knights. This is when you'll want to Super and use your grenades. Give the Wizard everything you've got, then crush its Ghost. When finished, follow the waypoint on your HUD to meet your contact, ending the mission.
