destruction baal is harder than many uberquests (since a few patches ago) . do not attempt it without at least half the charms and decent gear , and by decent gear i mean at least full mid-game / some end game items equiped . your damage is low by the way, that's why the fight is taking you so long . did you make the runeward in a sacred item or is it still t6 ?
also , 7k life???? did you do your challanges ? (ennead/BRC)
the "dark green" items are set items lol
by the way , the traprat was not yet revised for m2017 , so there could be 1 or 2 items replaced for mid and end game .
