Out of all of the trolling invader videos we've posted so far, this is my favourite.
Dark Souls 3: Hide and seek in PvP
As much as I dislike PvP in Dark Souls 3, without it we wouldn't have these kinds of videos. This is trolling invaders at its best.
The two guys in the video position themselves on stone plinths and use the Seed of a Giant Tree to blend in perfectly. Hilarity ensues as the two dark spirits run around like headless chickens trying to find them.
If you haven't tried out the PvP aspect yet, check out this primer to get up to speed.
