Halloween event

Boosts

While the Halloween event does not feature any inherent boosts for normal play, the associated Halloween quests (detailed below) feature large bonuses while played:

• +200% experience
• +50% drop anything rate
• +50% rare drop rate
• +100% rare enemy rate

These boosts are not affected by Ephinea's four rotating weekly boosts, and can only be further increased by playing the quests on Anguish difficulty.

Event items

Main article: Halloween Cookie

During the event, Halloween Cookies will drop from all enemies, regardless of difficulty or episode, at a rate of 1/2000 (with the exception of scared Rappies). Halloween Cookies will not drop from item boxes.

Associated quests

The availability of Halloween Cookies enable players to access the Halloween quests, which are are a series of single-area, single-room quests with extremely high enemy density for each area in every episode. For each episode, they are located in the "Halloween" quest category (Episode 1, Episode 2, Episode 4).

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), to represent "color draining from the world."
