Taken about 2 years but finally got all badges. Grandmaster score chaser was the hardest one for me. Had to complete with 7 challenges to get it. Doom slayer was tough too but when I got the right build I absolutely smashed yog for it.
Yeah I only had badder bosses on for that one. And youβre right, not easy with the extra mobs. I use a warden build and managed to get a good RoW run, loads of healing pots and a ring of furor+8 with a glaive, wand of regrowth with camouflage to keep away from everything.
