RoilAll Details
After charging, the Roil fires Bullets in a linear trajectory, dealing Kinetic Splash Gun Damage.
Using its unique Reduce Heat Firing Mode reduces ≈40% Heat. It still dissipates Heat passively.
Overheating disables Reduce Heat and firing without causing an automatic repair.

Weapons usually get one part per group, but sometimes multiple or none. Numbers in the top-right indicate the range of parts a group can have.
Parts usually have equal drop chances, or it's indicated nearby.
Dev Note:
Previously, if your gun was already overheated and you tried to reduce heat by switching firing modes, you were prevented from doing so and the magazine was effectively locked up. To change this, we’ve modified the timing of when the gun starts to repair.
