Guild Wars 2

Hello guys, I was wondering if anyone knows where every year there is the possibility of finding this skin in black lion chest.O if the only way you buy it.

No one knows if it will ever be available again. The wiki description suggests it won’t.

“This weapon skin is no longer available during Halloween. The skin was released during Halloween 2012, and was announced to have been the last chance to obtain the skin during the Shadow of the Mad King release.”

I thank you for your answer, even if ugly.
