Unused and Cut Content/Items

Icon	Name	Type	Quote	Effect	Ammonomicon Entry
	Master Round (VI)	Passive	Final Chamber	Probably grants an extra heart container like the five used Master Rounds.	This impossible artifact indicates mastery of the final chamber. A holy shell. Simply looking upon it bestows a great peace upon your soul. The Gungeon is at rest.
	Rat Master Round	Passive	?	Probably grants an extra heart container like the five used Master Rounds.	?
	Emerald Bracelet	Passive	Thrown Guns Return	Thrown guns return to the player. Unused since V1.0.0.	The emeralds in this bracelet are extremely jealous. They will force any thrown gun to return, just so no other hand can hold them.
	Sapphire Bracelet	Passive	?	Unknown effect. Unused since V1.0.0.	?
	Amethyst Bracelet	Passive	?	Unknown effect. Unused since V1.0.0.	?
	Cue Bullets	Passive	Bullet Kin, Corner Pocket	Enemy corpses gain significant knockback and can damage other enemies. Cut item from the Advanced Gungeons & Draguns Update.	Substantially increases knockback on kills; enemies hit by corpses take damage. Having given up on ever killing their pasts, many failed Gungeoneers pass the time by playing dumb games. Maybe one such adventurer missed playing billiards?
	Ring of Giant Strength	Passive	Throw Harder	Increases the damage dealt by thrown guns. Unused since V1.0.0.	Increases thrown weapon damage. This ring bestows incredible physical strength. Unfortunately, there are few benefits to physical strength in the Gungeon.
	Ring of Lightning Resistance	Passive	Grounded	Prevents electricity damage. Unused since V1.0.0.	Prevents damage from electricity. A ring originally worn by Alistair, the Thunderbolt. The gemstone set in the golden band is cracked down the middle.

	Fairy Wings	Passive	Enchantment?	Grants flight. Dodge rolling leaves pink slime that charms enemies. Unused since V1.0.0.	A pair of enchanted wings, which grant flight. Your caterpillar friend has metamorphosed into a wondrous creature! And that wondrous creature is a spine fly, which burrows into the spinal column of vertebrates. The survivors of this parasite sprout wings.
	Hunter's Journal	Passive	Luck Or Skill?	Slightly increased drop chance on room clear. A cut starting item for The Hunter. Unused since V1.0.0.	Slightly increases drop rate. Filled with maps and the answers to half-forgotten riddles. Ever since the Hunter was a child, she had a knack for finding things.
	Ceremonial Sword	Passive	The S Word	Unknown. Unused since V1.0.0.	A ceremonial sword. Not for combat. Bladed weaponry would normally incite the wrath of the Jammed, but this ceremonial sword is blunted and not for combat.
	Thirst For Vengeance	Passive	Taking You With Me	Killing an enemy right before death brings the player back to life. Unused since V1.0.0.	Slaying an enemy just before dying prevents death. Sometimes getting even is all you've got left.
	Bubble Shield	Passive	?	Deflect bullets for a few seconds, similar to Potion of Lead Skin. Recharges once every two rooms, unlike other active items. Strangely, it uses the sprite for Magic Sweet. Unused since V1.0.0.	?
	Old Infuriating Note	Passive	You’ve been had. . .	The cheese showing the direction to go in the maze is on the icon instead of in the Ammonomicon entry. Pre-AG&D version of the Infuriating Note.	You have been had. . . by the Resourceful Rat! Whatever was in that chest has already been taken by Gungeon's Most Wanted.
	Rock Bullets	Passive	?	Unknown. Possibly related to the Black Skusket (similar sprites) or the undiscovered desert chamber mentioned in the Cactus’s Ammonomicon description. Unused since the Supply Drop Update.	?
	Table Tech Time	Passive	?	Possibly slows time, similar to Table Tech Sight. Likely replaced with the Hidden Tech Time synergy. Unused since V1.0.0.	?
	Table Tech Table Flip	Passive	?	Possibly a Table Tech that would originally allow the player to flip tables, with Gungeoneers starting without this ability. Unused since V1.0.0.	?
	Unknown Table Tech	Passive	?	Possibly a Table Tech that would allow the player to electrify the nearby area. Unused since the Advanced Gungeons & Draguns Update.	?
	Table Tech Hole	Passive	Flip Oblivion	Possibly a Table Tech that created black holes like those made with Singularity. Unused since the Advanced Gungeons & Draguns Update.	This forbidden technique causes flipped tables to increase exponentially in mass, collapsing almost immediately. An apocryphal text of the "Tabla Sutra." Of that which we cannot flip, we must pass over in silence.
	Table Tech Life	Passive	Children of the Flip	Possibly a Table Tech that turned tables into temporary familiars. Unused since the Advanced Gungeons & Draguns Update.	This forgotten technique causes flipped tables to gain sentience, however briefly. An apocryphal text of the "Tabla Sutra." This ancient scroll invokes the tablegrammaton, the four letter name of table.
	Monster Ball	Active	100% Catch Rate	Caught enemies when used and then released them as charmed enemies when used again. This item is a reference to the Pokeball from the Pokémon series, which can capture creatures for use by the owner in battle.	Captures enemies and charms them upon release. Ancient monster trainers tried to use these balls to domesticate inhabitants of the Gungeon. According to local legend, Emmitt Calx threw one of these at a Beholster. It didn't work. However, it did force the beast to blink, which allowed Calx to escape.
	Scroll of Wonder	Active	Wondawondawonder!	Unknown.	A transformative spell of incredible power. The wizard Alben Smallbore theorized that the more power was put into a spell, the less could be known about its outcome. This spell is immensely powerful.

	Raccoon	Passive	Sly Scooper	Summons the Raccoon companion, which can carry players across trap rooms unharmed.	Helps to navigate dangerous areas. In another era, this Raccoon was a very successful thief. However, after dabbling in time travel, he became obsessed and put an end to his thieving career in favor of the infinite treasure of the Gungeon.
	Brittle Bullets	Passive	Risk/Reward	Ammo is lost upon receiving damage. Likely the same effect as Balloon Gun.	Greatly increases firepower. All equipped ammunition will shatter upon receiving damage. It takes an idiot to do cool things. That's why it's cool!
	Hero Sword	Active	Enter the Swordgeon	Upon use, spawns a sword facing the direction the player is aiming. Automatically recharges over one second.	An elegant weapon... though perhaps obsolete.

Lament Configurum	None	Eyeball	The code of the Lament Configurum contains an unused variable called 'ChanceToEyeball', permanently set to 0.001.
