 * {{Item|Night Revels Key|Key}} drops (and drops of {{Item|Piece of Darkest Chocolate|chocolate}}) are on a per monster basis
 * To maximise {{Item|Night Revels Key|key}} drops per person, it is advisable to run solo
 * Taking (multiple) hirelings into the quest will increase monster count, but all chocolate/key drops will come to the player character
 * To maximise key drops per minute, it is advisable to run the challenge at level rather than above level
 * Running at level +5 increases {{Item|Piece of Darkest Chocolate|Pieces of Darkest Chocolate}} end rewards, but means each kill takes more time, so is less efficient when running for Keys
 * Running at a challenge level below character level will decrease kill speed, so results in more kills per second (good for key farming, if chocolate and XP are a non-issue)
 * Killing all monsters in every area (even after star objectives are complete) provides more chances of key drops
 * Each area is blocked off by impassable mists until the previous objective is completed
 * Each "group" of undead is 6 undead (of any type) for a solo player (May scale with party size)
 * There is an entrance to the Night Revels Crypt just inside the entrance, allowing players to enter directly (to undertake other challenges) rather than needing to exit to House Jorasco

Walkthrough

 * Enter the graveyard and kill groups of undead until the first mist barrier (1) drops
 * Move into the central area and kill groups of undead until the second mist barrier (2) drops
