PvP Halloween weapons
From Guild Wars 2 Wiki
PvP Halloween weapons are the competitive mode counterparts to the PvE versions of the weapons released during each of the Halloween festivals.
Most of these were created by converting consumable Halloween weapon skins to PvP use. The craftable Halloween weapons (The Mad Moon, The Crossing, and Arachnophobia) couldn't be converted in this manner; their entries may only exist for parity.
