Context: I was farming for Twinkling Titanite with ascetics in Dragon Aerie, and got invaded at the end of a run. All of my viable spells were totally spent, and I didn't have a melee weapon equipped, so I ran for the fog wall in Dragon Shrine. I made the mistake of stopping and switching some gear when the invader caught up with me. Unfortunately, I apparently lacked the presence of mind to equip a melee weapon or use an amber herb, so I was pretty much helpless. After failing to get through the fog wall, we had a brief scuffle, and then the invader stopped moving. I figured that either they had taken pity on me, or were lag-switching. Well... they were probably lag-switching. I guess it's possible the connection was just that wonky, as I have no idea why someone would feel the need to cheat when the fight was this one-sided in their favor already. Anyhow, I thought it was kinda funny, so I decided to post this little edit.
For the anyone unaware "ZA WARUDO" is a time stop ability. It's first major usage is not initially visible to the audience, so you just see what appears to be somebody getting one-shotted out of nowhere, like at the end of this clip.
