It isn't hard to fix that issue.
simply remove the sorah chest's regen. by changing it to an Idle period on the "boss" instead of disappearing / reappearing to be another full "boss hp bar". meaning it doesn't heal itself either during that idle period. the rest of it is left alone. because the Sorah "boss" doesn't die. the extra spawns do kill people. and the "fix" should be implemented across the board. not that the first sorah has that issue because it isn't as bad. but come 95-109 and 125-135 sorah KQs we can see that issue so fix it so that everyone can get it done. lol. fixing the situation will completely stop that whole issue (snipping the bud as it were). and people can continue to level.
i totally agree. just stop it's regain. if it takes a run 20 tries to kill the chest cause of no dmg (picture those kqs where 8/10 are clerics) then so be it. but at least there's hope then instead of a dressing massacre.
