Recently, a bug has been found allowing anyone to One-hit KO any monster. How this is done is that someone casts Vengeance(or vengeance other) on themselves(or someone else). Then, the person who has the power of vengeance goes up to any monster, and MELEEs it. When the monster hits the person who has vengeance, even if they hit a 1, it will instantly kill them. A screenshot has been found showing someone hitting a 190 on a Black Dragon after being hit for 16.
