I've been playing the Guild Wars 2 Halloween event. I've done Act I, II, and III; I have the two books and the 10-slot trick or treat bag. I've done the Mad King Labryinth several times and the areas that the Lunatic Boatman can port me too (Clock tower, Lunatic Inquisition, Reaper's Rumble).
What else is there to do? Am I missing anything?
Aside from the costumes that can be purchased with gems; are there any other Halloween items I'm missing?
