PKMaster0036 is a player spoof and supposed master of Player killing seen during the Garden of Tranquillityquest. When a player uses the trolley on the statue in Falador, he is seen walking down to the northern entrance to Falador where two guards named Billy and Bob are discussing the life of a Falador guard. After a short discussion as to how their life usually lasts only 30 seconds and how people attack them completely unprovoked, PKMaster hits each of them for 220 damage for a one hit kill. He then buries their bones and continues on his way, allowing the player to push the statue out of Falador.
A question concerning him is also asked by the Wise Old Man when enchanting the Ring of Charos earlier in the quest. The question regards what to do if one encounters PKMaster in the wilderness and he asks them who the greatest PKer is; the correct answer being PKmaster himself.
