These 'special procedures' are functions assigned to objects, players, and locations to invoke a 'special procedure' when a specific event occurs. Proc is also sometimes short for 'spec_proc' ('special procedure'), used by the original programmer of Circle-MUD, Jeremy Elson and possibly the original programmers of diku-MUD as well. The term 'proc' is a programming term that refers to an event triggered under particular circumstances, or being 'processed'. (For those with extremely high Crit rates, you may not even notice much difference, but I wanted to call it out anyway. By reducing the proc coefficient from 0.25 to 0.125, the build still works and remains fairly strong, but it won’t be quite as good as it is now. Currently, this is used in combination with Critical Mass to lower the cooldown on skills like Frost Nova and Diamond Skin. In the case of Energy Twister, specifically Wicked Wind, the 0.25 proc coefficient causes the skill to generate more procs in a given time period than any other skill. Skills that hit multiple targets or pulse multiple times have lower proc coefficients.

Many skills (like Magic Missile) have a proc coefficient of 1. For players who may not know what proc coefficients are: they affect how effectively a skill triggers procs (or effects that have a small chance to activate). Energy Twister is having its proc coefficient reduced from 0.25 to 0.125.
