Listed below are all the slots currently in game that have a chance to proc an effect when a certain requirement is met. Each of these are how they happen but each item has a set percentage for how often it will go off. Breast Plate - When you get hit with normal melee damage. (currently also works for ae's) Feet - When you kick (all of the monk kicks do apply) Hands - When you are attacking with your bare hands. (also dragon punch) Bracer - When ever you cast a spell. Primary - When you attack with your main hand. Secondary - When you attack with your secondary weapon or when you use the skill slam. For shields it happens when you bash. Ammo - When you attack with your primary or secondary weapon. (excludes arrows and throwing weapons) Figured this should be somewhere on our forums.
