I still don’t understand when some of these interesting-looking proc chances can proc. For example, I recently found a Mythical Albrecht’s Duality, which gives a “5% chance of 51% CDR”. These and other skills which do not stipulate the conditions of proc (e.g. it does not say “x% chance on attack” or “on block” or such) base their % chance on what? 5% chance every second / full moon?

thanks
