50% is much more reasonable. That is good to hear. I ran it at level 50 with gear for that level. The Skeletons were annoying as they are now. In live it was a single heavy combo and they were dead. So 50% is reasonable. They don’t really hurt you at 50 that much, It is just annoying and long.
Though really a group at Level 30 to 35? in that case the lizards at the beginning really should be put back in, and 50% of what they are now is very much reasonable. If you just run pass the skeletons I can do it solo in the 20s easily.
I would recommend making the Vomit the boss does act like noxious gas down the line if it is supposed to be in the 30s. Right now it is just put up a shield walk back and forth run out of the way when it dives hit it with heavy combos rinse repeat.
Having it’s vomit create 3-4 seconds (heck go to 10) of noxious gas would cause an issue that the sandstorm mask (level 30 unlock) fixes which means for higher level players it is still a easy enough thing to do and would raise the difficulty for lower level players in a real way without doing so in a punishing way.
