UPDATE: this is the new v2.0, the crit chance part works, but im still trying to get the heal on crits working.

basically, imperials have 8% higher crit chance, and on a crit they heal 50 hp, plus every 10 levels it adds an additional 50 hp, so at level 10, crits heal you 100 hp, 150 hp at lvl 20, etc. maxes out at lvl 100 which adds 700 hp per crit!
