i havent played in over a year, what are lava cores and those heart things? i really just quested to 60 before i quit and didnt party much. made 2 epic pieces of gear and accidently bought 2 of the same epic ring wasting my souls (thats why i quit). i only knew to kill the elites for the souls at the time.
you need to lvl to 70 now and flame hearts and lava cores are to upgrade lava weapons to lvl 2 and then you need sigil to upgrade em further to legendary
