Oh boy, I thought I was the only one with this issue. I was in a level 480 temple against a Faith Healer... a couple buffs, but nothing too crazy; got through the first wave without issues (if there were issues, I didn’t notice them) then it was down to my bard and DM. They were dealing zero damage to Faith healer titan and pumpkin headed scarecrow wanker. After the first time through I assumed they were dodging or some goofy glitch was happening, but then I did it again with a similar lineup (Bard and DM were still active). Again, no damage to the same minions. Went back with completely different toons and finished it up without noticing any issues. Haven’t seen that issue again since, but it was annoying
