Fehu converted all items and pickups in the room into coins with value equal to their shop price.Kenaz poisoned all enemies in the room.Gebo used all machines and beggars in the room a couple times for free.Additionally, all of the Antibirth runes were cut.Stillborn, a Grimace variant who slowly floated towards Isaac while firing blood shots, then exploding when all other enemies were killed.Coil, an invulnerable Nerve Ending-esque monster who fired a continuous beam at any other enemy or Spike Ball in the room.Vessel, a Fatty variant who burst into a swarm of Tiny Maggots upon dying.Barfy, a Fatty variant who occasionally vomited a stream of projectiles towards Isaac.Furthermore, Mother (formerly The Witness) no longer spawns Corpse Eaters, which is just one of many changes to her fight. A variant of it which had a Bony riding it, named Carrion Rider, was also scrapped. Corpse Eater, a Grub-like worm who could kill other enemies during its charge, temporarily buffing it.Nightwatch, a ghost with a lantern that Isaac had to maneuver around, otherwise it would scream and summon a wave of enemies.Screamer, a slim humanoid who screamed if Isaac got too close, stunning him briefly, before it charged towards him.Exorcist technically still exists in Repentance, but only as a cameo for the Heretic fight, and is immediately transformed into a Fanatic. Necromancer and Exorcist, both humanoids who would summon Bonies and ghosts, respectively.Swapper, a Baby variant who fired a laser at Isaac and sometimes swapped positions with him.Strifer, a humanoid who could only move in two directions and fired blood shots if Isaac lined up with it, somewhat similarly to Wall Creep.Echo Bat, a leaner white bat whose projectiles temporarily reversed Isaac's controls instead of damaging him.Blind Bat, a white One Tooth who slept on the ceiling, before waking up and descending to chase Isaac.Fissure note not to be confused with the enemy of the same name from Downpour, a Trite variant who erupted blood projectiles in addition to its usual hops.However, their legacy is carried on via the Lil' Dumpy familiar. Dumpling and its variants, all floating heads who moved around by farting.In addition to items, several enemies from Antibirth were left out of Repentance, however some of them can still appear in the DELETE THIS challenge:.However, another unused trinket called Apple of Sodom actually did get implemented. On the double-unused side, an unused trinket called Salt Shaker could be found in the Antibirth files, but didn't make its way to Repentance.The knife was simplified to two pieces, rendering a third unnecessary.

Knife Piece 3, which was found in the Mausoleum.

They were probably cut since rock waves are no longer treated as explosions, although the effect returned in spirit with Brimstone Bombs that release a 4-way Brimstone laser.

Stone Bombs, which caused bombs to release a 4-way rock wave that dealt a lot of damage but could also hit Isaac.

Like Bowl of Tears, it was probably too abusable. Each lit candle would multiply your tears fired, but going past seven reset the menorah.

Menorah, a familiar that would gain a lit candle each time you took damage.

This was Samson's original Witness/Mother unlock, and was replaced by the Repentance-original Bloody Gust. It was brought back in spirit as the mechanic for Tainted Samson and the Berserk! item though, which gives an identical jawbone as a weapon during the berserk attack.

Donkey Jawbone, which made Isaac do a spin attack after taking damage.

Voodoo Pin, an active item that was functionally identical to Dull Razor, but wasn't returned with a new effect like 120 Volt was.

Possibly cut for being a little too strong.

Bowl of Tears, an active item that charged up when Isaac fired, similar to Isaac's Tears, and sprayed a Monstro's Lung-type blast.

It was likely cut for being just a bit too underwhelming.

Book of Despair, an active item that halved tear delay for the current room, surpassing the tear cap.

The binding of isaac item
