Proc Coefficient

From Risk of Rain 2 Wiki

In Hopoo Games Development Thoughts #1, the developers introduced the concept of proc coefficient. It essentially defines how strong or frequent procs happen on an on-hit basis.

"MUL-T’s nailgun has a low proc coefficient per nail of 0.4 compared to most character’s 1.0, so he isn’t proccing stuff a ton faster than other characters." - Quote from NaKyle, 03/30-2019.

Notes:

  1. 1.0 1.1 Technically has a proc coefficient, but it doesn't call the onHit event required to proc other items.
  2. It doesn't even do damage in the first place.
  3. Although the drones hit with a proc coefficient of 1.0, they have their own inventory and won't proc your effects.
