Well, Halloween Event is here in Tyria and there's so many things to do. I'll be posting up some links to good guides I've found that'll help out with doing all the Halloween Events(well, almost all).
Here are the guides that I've found so far:
1. Lion's Arch Pumpcin Carving Route
2. Scavenger Hunt Act 1 Guide
3. Random Stuffs in the World(Personalized Trick or Treat Bags)
I'll post more when I find them :) enjoy the festivities in Tyria!
