If you are trying to unlock everything your Graviton Spike Exotic hand cannon can do, you will need to track down a few hidden upgrade spots. These upgrades, called Intrinsic Upgrades, let you tweak parts of the gun like the barrel, magazine, and stock to make it even better. One of these secret locations is in the Stellar Sink, and finding it will bring you one step closer to fully powering up your weapon.
The Stellar Sink in Destiny 2
If you want to fully unlock the power of the Graviton Spike Exotic hand cannon, you will need to collect a few hidden Intrinsic Upgrades. These special upgrades let you customise parts of the weapon, like its barrel, magazine, and stock. There are three Intrinsic Upgrade locations you need to visit: Caldera, Stellar Sink, and Curtilage Divide. To know more about all the locations, read our article on “Unlock Graviton Spike & All Intrinsic & Catalyst Locations in Destiny 2”
The Stellar Sink Exotic Mystery Location
Next, in the Stellar Sink, fast travel to Assimilated Easement and follow the middle path down. Use Mattermorph to open the way, then take the Matterspark shortcut on the left side. Inside, look for a round door near a tall, overgrown pillar. You will find another strange plant on the ceiling. Use your Graviton Spike to shoot it like before, then quickly use the Matterspark shortcut again to grab the upgrade hiding behind it.
Head over to the Stellar Sink and check your map. You should see a marker labelled “Exotic.” Once you’re in the area, look up toward the ceiling and you will spot a glowing bulb. This upgrade lets you switch between two firing modes. Press the [Alternate Weapon Action] button to swap between a fast‑firing Arc mode and a slower, heavier Stasis mode. Getting kills or landing precision hits in one mode will charge up the other mode, unlocking extra effects when you switch.
