I ran this quest and during the quest I noticed that may of my weapons were taking excessive damage.
I swapped through weapon sets to take on various creatures (because my MinIIs are not done) and even before the end beholder both Tier II weapons were at 1/3 durablity as well as 2 other weapon sets. I have Fighter Defense II as well if that makes a difference and all weapons were piercers.
Anyone else getting this too.
