Ello move done both quests and for the potala one you have to do 30 purple runs, 20 green and 10 red you have to kill the three main bosses to get credit towards the quest and that's not the hard part, you have to do hundreds of runs to farm the dzi beads required to actually upgrade your wave to repel and that can take months as a casual player save the money and buy a repel +15 they are getting cheaper and are becoming very common.
My recommendation too. +15 repel weapons are in illusive now and more easy to craft with TS divine also. Plus all the big money now are on the new weapon and players will sell the old ones cheaper.
other weapons are ok, just the Bracers's price is crazily expensive If anyone has Repel Bracers +14 or cheap 15 please let me know your price then, thank you very much!
