Editing Halloween event (section)

===Halloween category===
The availability of {{Tool|rare|Halloween Cookie|Halloween Cookies}} enables players to access the Halloween quests, which are a series of single-area, single-room [[Quests|quests]] with extremely high [[Enemies|enemy]] density for each area in every episode. For each episode, they are located in the "Halloween" quest category ([[Quests#Halloween|Episode 1]], [[Quests#Halloween 2|Episode 2]], [[Quests#Halloween 3|Episode 4]]). 

While these quests may be selected at the [[Hunter's Guild|quest counter]] '''year-round''', each Halloween quest requires one member of the party to give one {{Tool|rare|Halloween Cookie}} to an NPC near the teleporter, in exchange for its activation, for the quest to be ''played''. Only one Cookie must be given to the NPC, and it can be given to the NPC by any member of the party; it does not have to be the party leader, and not every player in the party needs to contribute a Cookie.

Once the teleporter has been activated through the exchange of a Cookie, players will be teleported to a single room in the area of the quest chosen to fight through multiple waves of enemies.

: ''* Includes enemies from all [[Central Control Area]]''

While playing each quest, a black-and-white filter visual effect is applied to the screen (with the exceptions of [[Control Tower]] and [[Subterranean Desert]], due to both accessibility and technical reasons), to represent "color draining from the world."
