Effects that are in italics indicate that the effect is listed as the game's name for the effect, which is generally just a reminder.

Removed/Altered

Name	Items		Effect
Diazepam	Muscle Relaxant	Any of the following: A.W.P. Crestfaller Crossbow Hegemony Rifle Hexagun Laser Lotus M1 Shock Rifle Sniper Rifle Thunderclap Winchester Rifle	Damage of the guns is tripled. Nerfed in the Supply Drop Update to only grant a 50% damage bonus. Altered in the Advanced Gungeons & Draguns Update to affect fewer and different guns. The Crossbow's removal from this synergy was likely due to it being a starting weapon.
Hell Singing	Silver Bullets Crossbow		Increases the damage of Crossbow against jammed enemies by 50%. This bonus stacks with the damage from Silver Bullets, for a total of 487.5% damage to jammed enemies. This synergy is still in the game, but the capability for Crossbow to synergize with Silver Bullets has been removed, likely because it is a starting weapon.
King Bomber	Master Round I Lil' Bomber		Lil' Bomber's bombs become gold and spawn every time they hit an enemy. The synergy is still in the game, but the capability for Master Round I to synergize with Lil' Bomber was removed in the first patch after 2.0 due to being too easy to obtain.
Like Shooting Fish	Barrel	Any of the following: 38 Special M1911 Derringer	A fish pops out of the barrel and fires bullets. The last shot of each magazine fires a fish that flops around on the ground and fires at enemies. The synergy is still in the game, but the capability for the guns to synergize with Barrel has been removed.
Napalm B	Mega Douser Napalm Strike		Mega Douser's water spreads Napalm Strike's fire instead of extinguishing it. The synergy in the current game has been altered to spread all fire instead of just the Napalm Strike's.
	Dart Gun Mega Douser		Damage is increased by 25%. Removed in the Advanced Gungeons & Draguns Update, likely because it contains a starting weapon.
	Shock Rifle Battery Bullets		Shot speed is doubled. Removed in the Advanced Gungeons & Draguns Update, likely because it contains a starting item.
	Bionic Leg	Any of the following: Siren Trident	25% damage boost for Siren/Trident. Replaced in the Advanced Gungeons & Draguns Update with Brave New World.
	Klobbe AU Gun		The accuracy of the two guns is doubled. Replaced in the Advanced Gungeons & Draguns Update with Klobbering Time.
