Destiny 2‘s Graviton Spike hand cannon is one of The Edge of Fate‘s biggest post-campaign pursuits. This Exotic hand cannon blends Arc and Stasis, making it perfect for builds that use either element and even deadlier in Prismatic.
You must finish the Edge of Fate campaign before you can unlock Graviton Spike, since this weapon is tied to a few events that happen throughout the story. Once you cross off the final mission, The Message, interact with the Altar of Reality to unlock the Graviton Through the Ages quest.
That’s not the end, though: Graviton Spike also has three intrinsics upgrades and four catalysts at its disposal, which make the weapon even deadlier. We’ve outlined the major steps to acquire this Exotic hand cannon below.
How to unlock Graviton Spike in Destiny 2
Much like the post-campaign quests in The Final Shape, the quest for Graviton Spike will send you to a few different locations on Kepler, where you’ll make use of your new tricks to find some old tech for Lodi. The mission will take you to four different locations, with two stops: killing Vex as you’re near the end and doing a Sieve mission to obtain the Exotic.
You must use Kepler’s destination powers to find and scan a weapon piece in each of these spots. The first objective in each zone leads you to a general location where you must then find and interact with the weapon piece—usually with a puzzle or two along the way. Here’s where you can find them:
Triangulate the location of the weapon piece in the Outer Steppes
Land on the Outer Steppes and reach the main open area, then use the Mattermorph fungus on the far side of the zone to reach the Outer Wastes. Once the area changes, look on the cliff to your left to find a Rosetta Sentry by the tower nearby. Defeat it and use the terminal to reveal the location of the next part of the quest.
Follow your map marker deeper into the Outer Steppes, across from the tunnel you used to go into this area. When you reach the area where you fight off a boss Shank in the campaign, take the door on the far end, then enter the Matterspark shortcut. Inside, go up the ramp and jump across the gaps, then roll out of the ducts. Look across to find a house on the cliff, where the next piece of Graviton Spike is located.
Look to the left and charge the pylon on the ground, powering up a cannon right next to it. Take flight in Matterspark form, then find the remaining two pylons on your way: one when you land and another on the other side of the duct. Electrify all three to open the door to the cliffside shack and find the first DEO object.
Triangulate the location of the weapon piece in the Gorge
Land on the Assimilated Easement, look to your right, and climb onto the fungus-infested rock on the far side. Go past the two concrete cylinders and use Mattermorph to continue through the wall, leading you into the Stellar Sink. Land on the other side and hug the left wall, then look for a large hole also on the left to find another Rosetta Sentry. Kill it, then find the console on the other side of a Vex wall.
After killing the Rosetta Sentry, go back through the hole and take the Matterspark shortcut on your left, then hug the wall on the left to find another duct. Before emerging, note the hole on the left wall. The shaft leads to a rocky ledge across from a Vex wall.
Use Matterspark and jump across the gap, aiming for the small area between the concrete and the metal in the wall ahead of you, around where the blue Vex lights are. The ledge is big enough to fit a ball of lightning and leads to a secret room with a Mattermorph pickup.
Grab the Mattermorph pickup in this room, then return to the duct and go through the hole in the wall, which will now be just to the right of the entrance. Move the nearby objects to open a small area with the second weapon piece, then return to the Caldera.
Triangulate the location of the weapon piece in Exile’s Accord
Go to the Exile’s Accord landing zone and take the path almost ahead of you, on the right side of the Fallen hut, leading to Augur’s Bethel. Keep heading straight and make a left before the laser doors, then turn right just off the next area, past a pipe sprawling with fungus. Go into the Matterspark duct on the far side of the right wall, past a chest, and turn right once more.
Look to the left side of this Fallen-heavy area to find the Rosetta Sentry and a terminal in a small room. From here, turn around and take the same Matterspark duct you just used. Look for a train across from the duct, a bit further in the room. Go through it and pick up the next weapon part at the end of a short hallway. Get ready for a busywork objective, in typical Bungie fashion.
You must kill Vex enemies before progressing, gathering their data dropped as motes upon death. Harder enemies give you more data. You can pick any Vex-riddled area to do this in, though we recommend the Aionian Academy (northeast of the Caldera). Keep reloading the section, and more Vex will spawn. Kill them until you’ve advanced the next objective, which is also here.
Find the lost weapon piece in the Aionian Academy
The bright side is, all those Vex you killed counted as a triangulation, so you can walk up to the final weapon piece for Graviton Spike and grab it—provided you solve a puzzle first.
In the Aionian Campus’ main courtyard, destroy the Rosetta jammers and open up a door across from the spawn, which leads deeper into the area. Continue inside and you’ll spot a Relocator pad protected by lasers and guarded by an Imp Swarm, just before another patio crowded with Vex.
Clear the area and look on top of the crane on the right side, where you’ll find the Relocator inside a metal cage. Go to the locked door at the other end of the patio and turn around. The Mattermorph fungus is hidden inside a red pipe standing on the right side of the area, almost parallel to the entrance.
Interact with the Mattermorph node, then use it to bust open the way to the Relocator. Grab the modified launcher and go through the door, shooting it through the lasers at the door beyond. Turn around and to your left to find the teleport pad, land on the other side, and pick up the final piece. Your mission isn’t over, though: you still have another activity before you can get your hands on Graviton Spike.
Participate in the Sieve activity
The Sieve is only available for half an hour every two hours, so you might have to wait around if you don’t get lucky with your timing. The activity isn’t too difficult, though, and feels more like a public event than a challenge. You may have different objectives, such as banking motes or defending a point, but it should be over quickly. If you get a bonus round, try your hardest to complete it, since the rewards seem worth it.
