Salvation's Edge - Destiny 2 Guide

Once they're dealt with, head in and you'll need to Kill a Hydra and continue through the area as more doors open. Make note of the red squares on the ground as they will light up. But more on that later. Proceed through the first room, into the next room. If your doors are all shut, the other team likely needs to kill a Hydra to allow you to proceed. Once that happens, one team will need to find a Devotee of the Witness Minotaur that must be defeated. Once killed a Threshold Sentinel will spawn in the main room. Kill it to start the process all over again.

Once you've done the above a 2nd time, and killed the Threshold Sentinel you'll want to again break up into two teams and look for a glowing plate to stand on. Stepping on this plate will send a beam of light on the ground to the other plate another player will need to go to. Once you arrive, let the beam of light travel all the way along the ground and into the second plate. Watch the plate begin to charge up. It will make a sound indicating it's powering up. After only a moment, step on it briefly to send the charge back to the other side where the first player will let the plate charge up, and then send it back to the other player.

While this is happening, some enemies will spawn in the room as well as something called Pyramidal Resonance. Every player should pick up 3 of these if possible. The people managing the plate should keep passing the charge back and forth until there's around 30 seconds on the Final Shape Looming clock. At that point, you'll want to have one group shoot the spire's glowing yellow diamond to "lock" your plate. It will glow bright yellow if you've been successful. Step on the plate as it charges, and this time shoot it to "lock" your node. Once the nodes are locked, you can return to the main room. It will take one of your Pyramidal Resonance when you lock the spire.

Back in the main room, a Harbinger of the Witness will spawn. You'll need to kill it and a box will spawn in the main room, but it's a bit slow to do so after the Harbinger is defeated. Once it spawns, immediately put the Pyramidal Resonance you've collected into the box. This will extend your time and allow you to do the entire thing again until you've collected around 45 Pyramidal Resonance. Then it's onto the next encounter.
