Squash Serum

Squash Serum is an item included in the Halloween update. It is traded by the Necrid Horsemen in Ascalon City for 3 Charr Carvings, Lion's Arch for 3 Decayed Orr Emblems and Droknar's Forge for 2 Stone Summit Badges. It causes a translucent Jack-o'-lantern with a sparkling stem to appear around your character's head for a brief time. Squash Serum has no other effects.

It is unknown how long this will be included in the game. Most likely it will be removed after Halloween. This may make hoarding it now and selling it later quite profitable.
