係runescape，點囉果條【太極頸鍊】？

look at the map, near falador, there is a crafting guild. Then, you can see a place called dark wizard tower. you can see there is a sign of a face, the face colour is white and brown. You enter that shop and then talk to the guy in the shop. she said she can help you to change face colour, then you say that you want to buy her necklace, it is called yin yang necklace. It cost 100gp.

hope this can help you.
