Fall from Grace Compatibility

Fall from Grace is a MOD that currently features 2 new floors known as the Boiler and Grotto. The Boiler is a third alternate floor that can appear in Chapter 1.5 featuring its own enemies, bosses, and floor mechanics to go alongside Downpour and Dross. The Grotto is a third alternate floor that can appear in Chapter 2.5 featuring its own enemies, bosses, and floor mechanics to go alongside Mines and Ashpit.

Boiler Enemies

All Fiend Folio: Reheated enemies that can appear in the Boiler:

Name	Icon	Description
Morsel		Quickly chases Isaac. Usually found in groups of 2-4.
Slim		Slowly follows Isaac. When it draws close, it will attempt to smack him with its arm. If it hits a wall or an obstacle, it will stop to spray a few blood projectiles. When it dies, it has a chance to leave a Limb behind.
Limb		Remains stationary, hopping towards Isaac if he gets too close.
Pipeneck		Walks towards Isaac. Attempts to hammer its head onto Isaac when lined up in the cardinal directions, splashing projectiles where it lands.
Buckethead		Chases Isaac, boasting a high amount of damage resistance. Becomes a Frowning Gaper when the bucket is destroyed. Can appear as a second wave in rooms with overturned buckets.
Mr. Sub Horf		Chases Isaac. When it gets close enough, it will stop to spin its own head at him. The head will release projectiles in all directions as it travels. The head then becomes a Sub Horf, and the body becomes a Pacer or Gusher.
Archer		Emerges from pits, spitting a Monstro's Lung burst of projectiles at Isaac before leaping towards him. Fires four projectiles in the cardinal directions upon landing, leaving its tail exposed for a moment before burrowing.
Mayfly		Slowly flies towards Isaac. On death, fires two projectiles in a V shape towards Isaac.
Mightfly		Bounces around the room. On death, pops into three V shaped projectiles in a triangle shape, along with a fountain of projectiles.
Drop		Moves around the room by performing short dashes. Occasionally sinks into the floor, before attempting to land on Isaac from above. A blue mark will appear in the location Drop is about to fall in.
Dribble		Jumps in place, firing a spread of three tears at Isaac. Can perform a long dash, bouncing off of walls and obstacles. Splits into two Drops on death.
Shot Fly		Slowly flies towards Isaac. When damaged, performs a quick charge towards Isaac when lined up cardinally. Dies when it hits a wall while charging.
Shoter		Slowly flies towards Isaac. When damaged, splits into two charging Shot Flies in a V formation towards Isaac, when lined up cardinally. If killed before it attacks, will split and charge in two opposite directions horizontally to Isaac.
Spitroast		Slowly flies towards Isaac. Upon death, releases a ring of flames.
Spark		Moves around the room by performing short dashes. Leaves a small extinguishable flame behind with each dash.

Grotto Enemies

All Fiend Folio: Reheated enemies that can appear in the Grotto:

Name	Icon	Description
Milk Tooth		Flaps towards Isaac, occasionally making short, weak dashes towards him. Has very low knockback resistance.
Foamy		Drifts around the room, occasionally twitching. After a short while, enrages and makes a long diagonal charge, scattering projectiles when bouncing off walls.
Fathead		Slowly walks towards Isaac. On death, explodes into a large fart that deals no damage, and knocks back Isaac and other enemies.
Sniffle		Actively attempts to strafe around Isaac, while staying at a distance. Periodically fires fast, long-ranged bullets, attempting to lead them ahead of Isaac.
Roly Poly		Slowly crawls around the room. Rolls towards Isaac when he gets in its line of sight, bouncing off of walls and obstacles.
Centipede		Crawls towards Isaac, moving over any rocks in the way. Can crawl into pits to come out of another pit in the room.
Golden Fly Bomb		Quickly chases after Isaac. On death turns into a small golden bomb that explodes shortly after. Upon exploding, it reforms back into its default form. Pink Gold variant drops bombs that can be picked up and thrown. Cannot be killed by default - it will reform infinitely until all other enemies are killed.
Flickerspirit		Slowly flies towards Isaac. Possesses a giant blue aura that renders all other enemies inside it invulnerable. Isaac's attacks will pass through enemies inside the aura, as if they had piercing.
Eternal Flickerspirit		Orbits an enemy, rendering it invulnerable to damage. If all vulnerable enemies are killed, its target becomes vulnerable.
Viscerspirit		Orbits an enemy, boosting its health.
Shiitake		Remains stationary, periodically firing a small projectile at Isaac when he gets close. Usually found in groups of 2-5.
Ramblin' Evil Mushroom		Patrols around the room in a predetermined path. Occasionally spawns a spore which floats down, spawning a Shiitake on landing.
Cordy		Periodically leaps off screen to land onto any Splattercaps in the room, triggering its attack. If there are no Splattercaps left in the room, makes aggressive hops towards Isaac instead.
Splattercap		Remains stationary, splashing a large amount of red tears when a Cordy lands on it. If they are the only enemies left in the room, explodes into a damaging fart.
Mobile Mushroom		Slowly walks towards Isaac with its cap down, taking reduced damage. Will occasionally stop to show its face, shooting 4 projectiles in either the cardinal or ordinal directions.
Wobbles		Floats around and makes short dashes towards Isaac. Occasionally, makes a faster dash and inflates its body, sending it floating farther.
Cordify		Remains stationary, and periodically inflicts spores on a random enemy in the room. Enemies afflicted with spores explode into a poison fart upon death, which can destroy rocks. If there are no more available targets left, Cordify self-destructs in a large, explosive fart.
Stalagnaught		Spawns in the room burrowed under the ground, or hanging high above the room off-screen. When burrowed, attempts to repeatedly dig out directly under Isaac. When hanging, drops down when Isaac walks below it, indicated by its shadow. After dropping, digs down into the ground and begins behaving like the burrowed variant.
Speleo		Remains overall stationary but periodically attempts to leap on top of Isaac, marked the spot with a white reticle, creating a circular rock wave. If Isaac is moving, Speleo will try to predict his movement.
Cappin		Roams around the room, invulnerable to damage. When Isaac crosses line of sight in any of the cardinal directions from it, will quickly charge in his direction. Flips over onto its head after hitting an obstacle or running a certain distance, leaving its underside exposed and able to be damaged. Flips back upright after a moment.
Frowny		Remains stationary, occasionally spitting a single short-range projectile at Isaac. Has low knockback resistance, and can be pushed around without dealing contact damage. Is invulnerable, dies when the room is cleared.
Super Grimace		Remains stationary, and occasionally begins charging up a large projectile when Isaac is in sight and spits it towards him. This projectile splits into 4 projectiles in the cardinal directions on landing. Is invulnerable, deactivating when the room is cleared.
