Speleology—the study of cave-diving and spelunking. Yes, I know that’s the first question you’ve got when you see the Speleologist machine gun in Destiny 2, but what about its god rolls and best perks?

There are a few great picks for this machine gun in Destiny 2. The 900 RPM Solar Speleologist comes with an added benefit in the Radiolaria Transposer Origin Perk meaning kills with the weapon leave pools of Vex milk on the ground for enemies to walk into, taking extra damage over time. As such, it’s great as an add-clearing weapon and could even replace your primary, freeing you up for more boss-damage weapons in your Kinetic and Energy slots.
