In the last two weeks I have personally found three Jackal's Rings (+5 Listen) and four Lesser Jackal's Rings (+3 Listen), not to mention I saw three Necklace of Ears (+3 Listen) drop in a single Demonologists run.
Isn't this a little excessive? I'm not against this loot appearing in the game, but shouldn't it be rarer? Especially considering Move Silently is the hardest stealth skill to find gear for.
To compare, I've personally only ever seen one of the Hector's Bangles (+4 Spot) rings drop, and that was in Demonologists. Hide is also comparatively easy to get high, considering the availability of Camouflage scrolls.
Has everybody else been finding these items quite common, or have I just been unnaturally lucky?
