Thanks for investigating and testing my inquiry.. I was used to having my Water Dragon Pendant having fixed additional m.crit damage on top of the usual x2 m.crit dmg..
Was expecting Dragon Fire Pendants crit damage will do the same constant additional crit damage as well..sad
anyways, hoping for more experiments and testing on stuffs like this esp on L2 Store Items chances/odds GM Juji! Keep it up!
