The Resonance Disk is an item introduced in Risk of Rain 2
The item grants charge on kill, and when full, fires a projectile dealing
300% damage, while also piercing enemies. Afterwards, it creates an explosion dealing
1000% damage, ending with the original projectile flying back towards the user, dealing
300% damage along the way.
While holding the Resonance Disc kills generates
2.5 spin, visible by the dot in the model flying around. Spin decays over time. Every
1/60th of a second,
Spin = previous spin - (1.25 * time since last kill in seconds). In short, the spin decays faster the longer time between kills.
Spin, in turn, generates charge. Charge does not decay. At 100% charge, the resonance disc checks all enemies within the blast radius of its nearest target to see if it can hit more enemies by targeting one of them instead. After selecting a target, it will fire according to the earlier description.
How much charge is generated from spin is dependent on time since the last kill, and the current spin used as a vertical velocity with
-0.0125 gravity (so upwards).
- The Resonance Disc will also attack any nearby clay pots or barrels, which can prove fatal if you're in close proximity to one.
- Resonance Disc is Risk of Rain 2 equivalent to the Risk of Rain 1 item, Laser Turbine and is actually referred to as the
laserTurbinein the code.
