Seven-Leaf Clover

 is a passive item.

Effects

 * Increases the quality of chests found in chest rooms, mirror rooms and some secret rooms to an equal chance of red or black. (Essentially making it so you have a 50/50 chance of getting a red or black chest)
 * This item overrides the usual chance for Magnificence to decrease the quality of chests found in chest rooms.
 * Has no effect on chests found upon clearing rooms and items not found in chests.
 * Has no effect on synergy chests.
 * Has no effect in the chamber where it is found, only in subsequent chambers.

Trivia

 * This item is – and contains – several references to Futurama.
 * The item itself is a reference to Fry's Seven Leaf Clover, an object that gave him luck while he held it in the episode "Luck of the Fryish".
 * The "Breakfast Club" synergy is a reference to the record in which Fry hides the seven leaf clover in the same episode.
 * The Wind Up Gun, which is required for the synergy, is a reference to a similar wind-up weapon used in the episode "War Is the H-Word".
 * Though the item is called a seven leaf clover, the icon has four separate leaves.
 * The Seven-Leaf Clover also appears in the text-based game Kingdom of Loathing, where it grants lucky encounters.
