Ok so I've been playing dark souls for a couple days now,when I ran into my first invader.I was just a litte beyond the bonfire that is right after the bridge with the red dragon on it. I figured,ok I'm going to die now,that's fine.But after a few moments of staring at each other,he runs past me,I'm confused until I see that he shut the gate ahead of me,Before taunting and running off. (I did not know they could interact with my world like that...)Between that and all the jump off of cliff messages,I gotta wonder. How common is trolling like this?
