Each class has a tab at the bottom of the spreadsheet for their proc coefficients.
Proc coefficients are listed as both per hit and per second on separate pages.
PvP & PvE proc coefficients are exactly the same
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).
Every skill has a hidden "proc coefficient" that controls how special effects like Life on Hit play out in game. Proc Coefficients (PCs) can more or less be thought of as chance rates. The higher the PC, the more Life on Hit gained or the higher the chance to trigger a special effect. Specifically,
Proc Coefficients affect:
Life on Hit
Item effects (ie. Windforce Knockback)
Skill effects (ie. Wizard Critical Mass)
Life Steal is not affected
· Life gained from LoH = (Total LoH on gear)x(Proc Coefficient of skill used)
ie. A Demon Hunter with a 100 Life on Hit bow attacks a Zombie with Entangling Shot [Heavy Burden] (proc coefficient of 0.8). The Demon Hunter gains 80 Life on Hit (100*0.8=80).
· Chance of an item effect triggering = (Shown effect rate)x(Proc Coefficient of skill used)
ie. Using Multishot, Suppression Fire with a Windforce with 45% Knockback = 7.43% chance to knockback (0.45x0.165x100=7.43)
· Chance of a skill effect triggering = Proc Coefficient of skill used (no fancy math here)
The spreadsheet contains every proc coefficient in the game even damage over time (DOT) proc coefficients for skills like a Wizard's Meteor, and proc coefficients for the Monk's skills with multiple hits like Deadly Reach. This is a Google Doc spreadsheet, so it is limited in features. For this reason, the download to the Excel version is at the top of every class's page on the sheet. The Excel version has prettier formatting and useful things like showing which skills have the highest average proc rate for each class.
Also remember that many skills hit more often than others, and so they proc more often. Ie. Energy Twister on a Wizard is a great skill because of the number of times it ticks per second and scales with attack speed. So take the numbers here, and play with different skills to see which help you best for different situations.
PC = Proc coefficient
DoT = Damage over time
LoH = Life on hit
S/E = Skills/Effects (from items)
PP = Practical proc (Average 'amount of proc' per second for LoH or S/E)
The change log can be found at the bottom of the first Barb tab on the spreadsheet.
