Up until recently I had only heard of them and saw one video of one on youtube. That changed when I was going through my inventory one day counting weapons for Knight's Honor and realized I didn't have the Drake sword for some reason. So, I'm sitting under the bridge shooting the dragon's tail (third playthrough, just playing it safe) and I see what looks like a vagrant off in the distance.
After getting the sword I cross the bridge, and sure enough there was a vagrant near the bonfire there. I took my time to see what kind of attacks it had...the one I encountered looked like a dark sphere with some hair-like things sticking out of it, and 1 large claw like appendage...the claw attack was easily blocked but I almost died once when it shot up a barrage of stuff that homed in on me and I didn't block it all quickly enough.
Long story short, it only took like 2 hits to kill, for my efforts I got a small chunk of souls and a twin humanities. Was just curious how many of you have also seen these things, and if so what the drops were after killing them, as I've heard it varies depending on whether its a "good" or "evil" vagrant.
