Do they drop something since they match to your level or is this the new norm?

I've take down a few of those and haven't gotten anything other than the normal bonuses. It's kinda weird, it matches your level like an uncomon or rare, but isn't realy harder than any other mob your level and so far hasn't droped much of anything for me. I always take them out just in case they do but otherwise they're pretty much just a standard mob in my book.

have you tried looking at the wiki? it tells you there.

Yeah nothing's listed under it for drops.

Then that means it drops nothing.

Wrong, Zophah. That just means that no one has FOUND a drop for it yet. The wiki is actively edited by quite a few people, but I think Dan is perfectly content to let us edit it while he performs his game-running magic. Meaning: We don't know what's dropped by these guys. Maybe nothing, maybe a lot.

Or mabye just something in the future, if Dan decides he wants another uncommon/rare npc.

Just killed one. Still no drops. The XP reward - 40 XP - is actually the highest non-boss XP reward that I know of though...
