Procs and how they work

Does the level of the IO effect the damage of a proc?

No, the damage from procs varies by Combat Level, and has no bearing on the level of the proc IO, nor which proc. They all do the same damage, however the damage type of each proc does make a difference due to Enemy resistances. The Smashing and Lethal damage procs are more often resisted than the other damage types.


What is the chance of the proc firing?

All Damage procs have a 20% Chance of firing except Touch of Death which only has a 15% Chance.
The more you use a power with a proc (such as in fast-recharge attacks), the more often it will succeed. I11 added in new procs; the Purple Recipes, their procs all have a chance to fire of 33%. While the new debuff/knockback procs have the standard 20% chance of firing

How does a proc work in (Insert Rain/Emanation Power)?

A proc will have a chance to fire once every 10 seconds for the duration of the Rain/Emanation Power. For a power that only lasts 10 seconds, it will get two chances off (Tested this myself and confirmed).

What happens when multiple enemies are hit by a proc?

The proc is calculated separately for each enemy. This means if you hit 10 enemies with say, Buckshot, then on average two enemies will be effected by the proc.
