So i’ve never seen this for myself, but there were screenshots in the early wom days of the hero/villain mini bosses dropping amulets that were EXACTLY on their level. This means that they could drop amulets at impossible levels, since the ones-place level could end in integers 1-9 which is impossible for any other items. Plus, you could get them at higher levels than the current cap, which is also impossible, since you can only obtain items up to your current level, every 10 levels.
So what happened to these amulets? Were they left unchanged, reverted to level 90, or deleted entirely?
