Its the thing u get from squeel of fortune Or however u spell it, its non tradeable u cant alch it or die in wild, its pointless just like those robes from SW XD
It turns you into an ugly mother fucker...
OT: It's a tattoo that Runescape decided to put on the Squeal of Fortune which makes you bald and patterns your head when worn. The value isn't worth it. Can't alch, sell or trade it.
Well, not sure if the event is over but if you post on a Runescape Forums with your avatar having this tatto, you may be lucky to win a life-time membership from Jagex.
