I'm generally a nice player, but if I'm trying something out with the intent of messing with people, I can do some nasty things.
Demons' Souls comes to mind more than Dark Souls, as I remember making a build with the express purpose of invading other players and laying as many status effects as possible, while also trying to break their gear. So, naturally, I did a lot of invading in the Valley of Defilement's poison swamp. I invaded this one player's world, and he had two blue phantoms helping him. So, naturally, I rushed ahead of them and got to the shanty town at the end of the level and waited on a ledge. The moment they passed I shot an Acid Cloud at them to start breaking their gear, followed by a Death Cloud to plague them. Anyone who's been in that section of the game knows that the camera's a ***** at the best of times, and all of these clouds didn't help, so I ran up behind one of the phantoms and backstabbed him--immediately killed him. The other two players ran out and I chased after them and killed the other phantom with a roll-backstab. The host had just cured himself of plague when I ran up and killed him by stunlocking him in an R1 spam. Surely people have done worse, but it's still a dick move to kill someone at the very end of this level--especially just before they open the shortcut.
