And welcome to my first guide. This will probably be my only, still. This guide will basically just cover the enemies, the items and the rooms. ALL the floors in The Binding of Isaac are randomized, except for all the 2nd floor bosses starting with The Depths. Without further ado, let’s begin! PS: Excuse my English if you find a grammar mistake, it’s not my native language IMPORTANT NOTE: Whenever you read WotL, it means it’s exclusive to Wrath of the Lamb, the official expansion. LESS IMPORTANT NOTE: When I say XXX, I actually mean ??? C1.0 Enemies Otherwise known as monsters. You must defeat all of them in a room before continuing, although you can bomb your way out of them. This section will list all of them, along with their behavior. C1.1 Regular enemies Black fly A black dot with wings Harmless, can’t do touch damage, can be defeated on one shot, may turn into a Pooter. Attack fly A red flashing fly Can do 1/2 heart with touch damage, it takes 2 tears to kill. Moter 2 conjoined attack flies Requires 3 tears to kill. Separates into 2 attack flies upon death, unless killed in one hit. Eternal fly (WotL) White fly They circle corn poop or certain enemies, like the Hanger. They don’t change movement patterns until the poop or enemy is destroyed. Before that, they deal 1/2 heart damage and can’t be destroyed. After their host is destroyed they turn into large Attack flies. They are immune to the effects of Skatole. If they are circling around Poop you can leave the room and, when you come back, they will despawn. Pooter Black fly with eyes and a thorax It doesn’t deal touch damage and it doesn’t follow you. It launches blood balls which deal 1/2 Heart damage, it may appear from a black fly. Fat fly Similar to a Pooter, but with a bigger pink thorax Same health and damage as a Pooter but launch blood balls on a V-pattern; it may spawn in place of a Pooter. Boom fly A big ball with legs, wings and a face They explode on death, they don’t chase you actively, but bounce of wall and deal touch damage. Red boom fly Red boom fly with cheeks inflated They release 6 projectiles on death, but don’t explode. The projectiles always have a set trajectory. Sucker A black fly with a red body They try to deal touch damage, they release 4 projectiles on a + pattern on death.

Spider (WotL) A red dot with legs They run towards Isaac. They are unaffected by webs, and can walk between the corners of the rocks. Big Spider (WotL) A spider with a big black thorax They have more Health than regular spiders. Like Moters, they spawn 2 Spiders on death. Trite (WotL) An upside-down Isaac head with 4 eyes and legs They leap towards Isaac. They can cover a lot by jumping, but they also wait a LOT (About 2 seconds) before leaping again. Boil It looks like... a boil They start as a small sphere, but it begins growing. At full size, they throw blood balls. If hit, they’ll shrink, but grow back if they aren’t destroyed. Gut (WotL) A green boil They throw green balls (Like Spits) at close range. Sack A white boil/gut They spawn Spiders but don’t attack normally. Walking Boil/Gut/Sack They look like a Boil/Gut/Sack, but with legs They attack just like their normal counterparts, but they walk. They also don’t regenerate health. Mulligan Crying people with a bloated head They don’t attack, they run from the player (Even running into dangers to do so), and they don’t deal touch damage. They might explode and release blood on a + pattern, along with 2-4 random flies. Mulligoon Mulligan with sewn eyes They behave like Mulligans, but shoot blood on an X pattern and leave a troll bomb. If they explode on their own, they shoot 6 projectiles. Mulliboom (WotL) Mulligan with a bomb stuck on its head They chase you and explodes on touch, dealing 1 Heart damage. They also explode when killed. Hive Mulligan without eyes, an open mouth and holes on its head They act just like Mulligans/Mulligoons, except they don’t explode, and they cough up flies. When killed, they spawn 5 red flies. Swarmer (WotL) The decayed head of a Hive, surrounded by flies They spawn regular flies, but will spawn a Pooter or a Fat fly upon being hit. When killed, they spawn a Boom fly. They are also immune to the touch damage quality of My Little Unicorn. Hopper A headless body, always facing to the front (Similar to Isaac’s) They jump around the room, and can jump over rocks or other obstacles. They follow Isaac only when he’s near them. Flaming Hopper A black Hopper with a flame where the head would be, unless it was a Champion, in which case it will be a darker shade of the original (Even the flame) They spawn when they touch fire. They have more HP, double speed and leaping range and follow the player from longer. Leaper A Hopper bleeding from the neck They have a better sense of where is Isaac. They can leap high into the air and then launch blood on a + pattern. Pacer A slightly fat body bleeding from the neck They walk around blindly and don’t deal damage (Except touch damage). They spawn when a Gaper or Mr. Maw is killed. Gusher A Gaper with blood gushing out of his neck They shoot blood balls. Gaper A smiling Isaac crying blood They try to touch Isaac via the most direct route. If there is no way to reach Isaac, it stands still until a path opens. They may turn into a Pacer or Gusher before dying. Frowning Gaper Like Gapers, but with their eyes closed. When they get close to Isaac, they open their eyes (They don’t have eyeballs). They’re quicker than normal Pacers, and have a bigger chance of spawning a Pacer or Gusher. Gurgle (WotL) Green Frowning Gaper with eyes already open and a bent neck They don’t turn into Pacers or Gushers on death, but they shoot green projectiles (Like Guts), but it’s somewhat inaccurate. Mr. Maw A Frowning Gaper with eyes open and a bigger mouth When it’s near you, it launches its head (Still attached). If the body is killed first’ it turns into a Maw.

Globin A body make of muscles without eyes and a big, open mouth They follow Isaac, and, when you kill them, they turn into a pile of goo, which must be destroyed before the Globin regenerates. Gazing Globin A Globin with eyes It’s faster, does more damage, is stronger and runs away from the player when in goo form. Knight It looks like a shopkeeper from the front, but it has its brain exposed from behind It’s invincible from the front, but not from behind. It turns to Isaac when shot or if he’s near. You can use Cupid’s Arrow to damage him from the front. Selfless Knight Like a Knight, but with a mouth wide open and Isaac’s face in the back of the skull When they see Isaac, they will charge towards him. Mask + Heart (WotL) Like a Scream mask with a heart below it The mask is invulnerable, but the heart isn’t. The hearts shoots on a + pattern when Isaac is near. Clotty A piece of meat with eyes and a bone It moves in random directions, shooting on a + pattern. Clot A black blob with yellow eyes, somewhat similar to Gish It shoots on an X pattern. I.Blob (WotL) A white crying blob It shoots in all eight directions Maggot A maggot with eyes without pupils They are blind and don’t follow you. They can’t shoot, either, but they deal touch damage. Charger A Maggot with black eyes and an open mouth They move randomly until Isaac is within range, where they will charge towards him, until they reach a wall.

Licker (WotL) A head with its tongue sticking out and chained to other B. Lickers They are similar to Larry Jr. but when a one is destroyed, they ALL separate. Parabite A worm with a big mouth They move around until they spot you, where they will charge and deal 1 Heart of touch damage. They may go underground and pop up anywhere, although they can’t pop up right under Isaac. Fred It resembles a smaller version of Scollex They launch a green projectile. He can also jump out of the ground, dive back in, launch an X pattern blood shot and resurface anywhere. Lump A lump of muscles with a face It pops out of the ground, shoots blood, and dives back in. Leech A parasite resembling a... leech They behave EXACTLY like a Charger, only they are flying, thus, they won’t stop for rocks. They are also faster. Kamikaze Leech A black leech with an eye on its mouth They explode on touch or death. Holy Leech (WotL) A white Kamikaze Leech They are identical to a Kamikaze Leech, but they have an Eternal Fly around them. Host A skull filled with intestines They are invulnerable when retreated, and never deal touch damage. They may rise up and shoot three blood balls. Red Host A Host with a red cranium They can be damaged anytime, but they shoot more frequently and also shoot 5 balls.

When the player is in line, it will shake and launch a blood beam that travels over obstacles and lasts a few seconds. Double Vis (WotL) A slightly paler Vis with a bloodstained chest and another opening on its back It can shoot a beam from the back to. Chubber (WotL) A Vis with a small, green, mouth less head (The head looks like a worm) It shoots a small worm that deals 1 Heart of damage instead of the blood beam. When destroyed, the worm must be destroyed too, or the doors won’t open. Poky A brown spiked block It moves on a horizontal or vertical line. It’s immune, to destroy it, you need to kill all other monsters (It can help you on this task: It damages any enemy it touches) Slide (WotL) A blue Poky It’s stationary until Isaac lines up. They will begin charging, damaging any enemy it touches. It stops when it touches anything solid (Rocks, a wall, another Slide, etc). It’s not despawned even upon clearing a room. Eye A nerve-covered eye Doesn’t move, it follows you with its view and shoots lasers when you stop. Bloodstained Eye A clean, white eye They shoot the laser shot by Vis. Dople Isaac made of muscles They mirror Isaac’s moves and tear shot exactly. The only way to defeat them is to outsmart it (For example, making it hit spikes, fire or another enemy), using a familiar, Mom’s Knife, invincibility items such as My Little Unicorn, or a bomb. Evil Twin A black, flying demon with 3 red eyes It flies, so it can’t be killed by spikes, but its shots are slow, so it’s easier to damage them. Embryo A fetus-like, hopping creature (Similar to Blastocyst) They usually spawn in groups of 4, and have a health bar. Baby Floating baby ghosts with a bloody mouth They float around shrieking and shooting. They can also teleport, usually near to Isaac.

C1.3 Bosses in the Cellar Widow A spider with an upside-down head Attacks: Jumping around like Monstro twice as far, spawning Sacks, spawning spiders and generating white goo which slows you down.

Ghost: Stands still, shoots a blood beam when you go near. Can’t be damaged, but it dies when you kill the zombie. Gurdy Jr. A pile of guts, fat and other body parts and fluids. Gross.

Champion forms: Blue: A smaller Gurdy Jr. appears in the room. They can only attack by charging Red: She can only spawn Fat Flies and charge. She has more HP and is bigger C1.4 Bosses in the Caves Fistula It looks like a broken moon rock to me Attacks: It begins as one, but divides into 4 parts after being damaged (Similar to Envy). After a part is killed, it becomes a Charger. Champion forms: Violet: It divides into 3 instead of 4 parts; it’s slower and spawns a Boom Fly on death Gurdy Similar to Gurdy Jr. Attacks: She goes into her body mass, and appears on a side. Then, she throws blood balls (Pretty annoying). She can also spawn flies, Pooters and Fat Flies. When she raises her arms, she summons 2 boils in front of her (More annoying). Champion forms: Sick-green: She doesn’t shoot blood, but she continuously spawns flies Peep A (very) fat man Attacks: He jumps and tries to land on you, a-la Monstro.

C1.5 Bosses in the Catacombs The Carrion Queen A skeletal worm with a fleshy spot at the back Attacks: An alternate version of Chub, but she can’t spawn monsters. She can only be damaged by hitting her at the back, or feeding her bombs. She also spawns Red Poop which damages you on touch. Champion forms: Pink: Smaller and can’t move diagonally. She also spawns hearts which fire on an X pattern instead of Poop. Killing the hearts damages her. The Husk A posthumous version of The Duke of Flies, it looks like a skull Attacks: Same as The Duke of Flies. It’s faster, spawns Spiders along with Flies, and it also fires Blood. Champion forms: Black: Spawns Boom Flies and periodically shoots blood in all directions. He leaves flies and 2 Boom Flies on death. Pink: He never spawns enemies, but he shoots on all 8 directions constantly. He spawns Flies and 2 Red Boom Flies. The Hollow Guess what... another posthumous version. This time, it’s Larry Jr. Attacks: Unlike Larry, The Hollow moves diagonally, and can fly above rocks. Other than that, he’s exactly like Larry Jr. Champion forms: Gold: Drop coins when you destroy a segment Black: Spawns Boom Flies when you destroy a segment Green: Shoots blood and, when a segment is destroyed, it spawns a Charger The Wretched Ding, ding, ding. Another posthumous version. Guess which one. Like Widow, only her mouth has been sewn shut, but another one has appeared on the bottom Attacks: Like Widow, only she spawns a set of 2 Spiders, a Double Spider, or a Trite. Her puddle of white goo is larger, and she shoots white balls (Of that substance cobwebs are made of?) while she spews the goo. C1.6 Bosses in the Depths Monstro II You’ll never guess... Attacks: The blood cough has been replaced with a Shoop da Whoop-like lazor. Also, his jump has been altered: First jump, he shoots blood that deals 1 Heart of damage. Second jump, he spawns 4 Suckers. These alternate. Champion forms: Red: Smaller and he only spawns 2 Suckers. He’s faster Loki A red imp Attacks: He shoots on a + pattern, X pattern, the + pattern again. He also shoots on all 8 directions, and teleport. He’s also accompanied by a Poky. He can also spawn Boom Flies. Gish (Unlockable by clearing the Depths 15 times, replaces Monstro II) A black Monstro with yellow eyes and sharp fangs, one could say it resembles a Clot (Reference to another Edmund McMillen game, Gish) Attacks: Instead of FIRIN MAH LAZOR! He shoots a black ball that leaves black goo which slows you down. He also spawns Clots and the first jump doesn’t shoot projectiles. Mom A foot, eyes, a hand or a lump of flesh (Depending on her current attack) Attacks: It depends on the body part she’s currently showing: Foot: She stomps you. Hand: She slaps you when near any of the doors. Eye: Nothing. Yes, nothing. Flesh: She spawns enemies. NOTE: Using The Bible is an INSTA-KILL. Don’t hesitate in using it unless you want a challenge. C1.7 Bosses in the Necropolis Mask of Infamy A mask with a heart Attacks: The Mask is invulnerable, the Heart isn’t. The Heart occasionally shoots blood on 8 directions. The Mask charges at you.

Daddy Long Legs A spider with 4 feet (It looks as if it were hanging) Attacks: Stomping all 4 of his feet, stomping one at a time, coughing up Spiders, slamming his head and shooting blood in all 8 directions. The Bloat Posthumous version of Peep Attacks: The same as before, but he begins without his eyes, piss being replaced with blood, and shooting blood from his eyeholes. Champion forms: Green: Launches 3 green balls after landing, spawns 2 Chargers after pissing blood, less HP. Triachnid (Unlockable by clearing the Womb 15 times, replaces Daddy Long Legs) A grey DLL with one eye and 2 black fangs (Reference to another Edmund McMillen game, Triachnid) Attacks: Same as DLL, only he has 3 feet, he leaves white goo and he spawns Trites. C1.8 Bosses in the Womb Scolex Posthumous version of Pin Attacks: The same as Pin, except he might poke out his head and launch 3 green balls. Blastocyst A fetus in amniotic liquid Attacks First, he might either do a low hop and shoot blood on random directions, or a large jump which launches blood in all 8 directions. He divides in 2 upon taking enough damage. Then, he shoots blood in either an X or a + pattern after jumping and divides in 2 after taking enough damage (4 Blastocysts). Then, he only fires in a + pattern after being still. He doesn’t shoot after jumping. Then, he divides in 2 Embryos (A maximum of 8 Embryos). Mom’s Heart A heart Attacks: Summon enemies and retract. Until 33%, when she doesn’t retract. It Lives! (Unlockable by clearing the Womb 9 times, replaces Mom’s Heart) A heart-body Attacks: Same as Mom’s Heart, but it summons bosses. C1.9 Bosses in the Utero Teratoma Posthumous version of Fistula, it looks as if it had teeth Attacks: Same as Fistula, only she divides into 3 instead of 4 and spawns Spiders when the smallest part is destroyed. Lokii Loki divided in 2 Attacks: Same as Loki, only they spawn Red Boom Flies. C1.10 Bosses in the Sheol Satan I don’t need to describe it ¿Right? Attacks: This is it. The final battle. There are 3 phases to it. First phase: He summons the Fallen. Second phase: 2 blood streams (First 5 then 4), shooting a blood laser from his mouth, and firing a blood beam from each hand. The latter two only happen when you are directly in front of him. If his eyes are open, he shoots from his hands. If they are closed, he fires from his mouth. Third phase: He stomps like Mom. C1.11 Bosses in the Cathedral Isaac ZOMFG I DUNO Attacks: Like Satan, there are 3 phases. First phase: He’s in fetal position. He shoots 12 tears on a radial burst and retaliates with a stream of tears when hit. Second phase: He stands up, crying. He shoots purple tears on all directions that home slightly and also retaliates. Third phase: He grows angel wings and starts flying, smiling. Beams are shot from the ceiling, Angelic Babies will appear, and the same purple shots are shot in 6 directions. He no longer retaliates. C1.12 Bosses in the Chest XXX Like the character XXX Attacks: Same as Isaac. Yes, everything. C1.13 Bosses that appear anywhere The Fallen A fallen angel Attacks: Chasing you, firing blood beams on a + pattern, shooting 2 salvos of blood (First 3, then 4) at 50% health, he will divide in 2. Krampus It looks a bit like a bat (He only appears in Devil Rooms) Attacks: Spitting the 2 salvos of blood, firing beams on a + pattern. C1.14 Mini-Bosses Envy A floating fella with a troll face Attacks: Touch damage, divides in 2 after taking enough damage, then those parts divide in 2 each (4 Envies), then, they divide in 2 each, this time with a ._.

Super Envy (WotL) A blue Envy Attacks: Like Envy, but divides in 3, then 3 again (9 Super Envies), then 3 again (27 Super Envies OMGWTFBBQ) Gluttony A Vis with a head Attacks: Same beam as a Vis, also shoots on all 8 directions Super Gluttony (WotL) A Double Vis with Gluttony’s head, but vomiting blood Attacks: Same as Gluttony but with another beam from the back, shooting blood similar to Monstro’s cough. Greed A shopkeeper that somehow avoided being hung (He appears in shops and Secret Rooms) Attacks: 3 arrows from his mouth, spawning Hoppers. The blood or touch damage makes you lose 3 pennies: 2 are dropped and 1 disappears. Super Greed (WotL) Greed with a coin on each eyelid and a $ sign on his forehead Attacks: Shooting 4 blood balls and spawning Keepers. He stills makes you lose pennies. Lust A pink Isaac under effect of the Virus (Many weals) Attacks: Only touch damage. Don’t get me wrong, she doesn’t has any attacks other than touch damage, but she’s pretty darn fast, and won’t stop for anything except losing sight of you. Super Lust (WotL) Lust with a lot of punches and a bullet shot on her forehead Attacks: Same as Lust, but she’s extremely fast and leaves a trail of blood that damages you. Pride A grey Isaac Attacks: He can either put a Forever alone face, which means that he’s about to shoot beams (Not blood beams, they’re very thin) in an X pattern, or put a Troll face, which means that 6 Troll Bombs will spawn (He’s immune to them). It’s probably the easiest sin. Super Pride (WotL) Pride, but pink (I think it represents gay pride) Attacks: Same as Pride, but the beams are in a + pattern, and 2 Mega Troll Bombs (which follow you) spawn instead of 6 Troll Bombs. Ultra Pride (WotL) Hard to describe, but it’s green and resembles Edmund McMillen with a familiar that resembles Florian Himsl Attacks: 3 homing projectiles, a horizontal line of green goo that deals touch damage, and the familiar shoots one homing projectile. Champion forms: Green Florian: His attacks deal 1 heart of damage Sloth A green Globin Attacks: Spawning a Charger, shooting a green explosive ball. Super Sloth (WotL) A green Gazing Globin Attacks: He can shoot 2 green balls and spawn 2 Spiders. Wrath A man in a grey suit Attacks: Shoot bombs, but he’s so stupid that he doesn’t run from the bombs even though they can damage him. Super Wrath (WotL) His suit is burned, he’s bigger, and he has a mouth Attacks: He drops Mega Troll Bombs instead of normal bombs. C1.15 Harbingers Note: They are only unlocked when you defeat Mom for the first time. Famine (The Basement) An eyeless, starved man Attacks: First phase: He charges, goes through the wall, and comes from the other side, then spawn a Pooter or Fat Fly. If there are Flies on screen, he only charges every 10 seconds or when you align to his left or right. Second phase: Only the head is left. He fires 3 blood balls. Champion forms: Blue: He shoots blood on 6 directions (Minus vertical), charges slightly diagonally, and then does a full circuit around the room. He can also shoot blood like Monstro in the Second phase. He can’t spawn flies. Pestilence (The Caves) A green corpse Attacks: First phase: Firing a green ball, leaving a green puddle and summoning Chargers and Spitties. Second phase: he loses his head. He still leaves the goo and spawns red and black flies Champion forms: White: The First phase summons Trites and shoots white balls on 6 directions. The goo turns with and just slows you down. The Second phase still fires the 6 balls and also summons Spiders. War (The Depths) A skinless man Attacks: First phase: He charges like Famine, but he does 3 runs, always coming slightly below his starting position (Unless he would be bellow the room when he comes back, then he would come back at the top, shooting on all 8 directions, and dismounting, summoning 6 Troll Bombs, the mounting again. Second phase: He loses his horse. He chases you like Lust and Gemini, and like the latter, he stops to catch his breath. Also, damaging him slows him down.

Death (The Womb) An armless skeleton Attacks: First phase: He either summons 4 scythes that go around the room, or 2 that follow you. He can also use the Hourglass (See Items).

Attacks: His head can charge across the room (Like War), shoot green bombs and leave green goo (Like Pestilence), Firing three shots at you (Like Famine), and summoning Knights (Like Death). C2.0 Items There are 5 types of Item: Activated Items: They are stored on your Spacebar slot, and can be used once every a specific number of rooms, or instantly, like Kamikaze, but these ones usually have a cost, normally Heart damage. You can only hold one at a time. Passive Items: You can hold many at once, and they grant you a passive effect. There are 4 kinds, according to Ed (http://edmundmcmillen.blogspot.com.ar/2011/09/binding-of-isaac-gameplay- explained.html): Weapon Items: these alter your tears in some way Stat Increasing Items: These increase your stats Passive Items: These ones alter other aspects, such as flight or accessing Secret Rooms anytime Familiars: These ones are divided into types as well: Spawners: These spawn a specific type of Pick-up Extra Lives: These ones give a specific amount of lives Shooters: These ones follow you around shooting alongside you Orbitals: These ones, instead of following you, orbit around you Unique familiars: There are only two: Cube of Meat and Guppy’s Hairball Trinkets: They’re a combination between Activated and Passive Items: You can only hold one at a time (Two with Mom’s Purse), but they grant you a passive effect, usually changing some odds. Tarot Cards: You can only hold one at a time and they use up your Q slot. They don’t have any difference from Activated Items, except being on another slot and thus being able to hold one of both. Pills: They increase or decrease your stats, or use an attack such as the Bad Gas. Note that the first time you pick up one, you don’t know their effect until you use them, and that the color doesn’t identify a Pill in different playthroughs, but same color means same Pill in the same playthrough.

C3.7 Curses

At the start of the floor, there’s a chance to get a curse, which makes the 
floor harder in some way.

Curse of the Lost: Increases the size of the floor by some rooms
Not really bad

Curse of Darkness: Makes you unable to see the map

Curse of the Labyrinth: The 2 floors are combined into one big floor (Called 
XL, for example, Cellar XL)
There are 2 Item Rooms and 2 Boss Rooms, both of which must be defeated in 
order to proceed
Sometimes, there might be 2 areas that are only connected by the Secret 
Room. If you have no bombs or Greed spawns in it, then you won’t be able to 
complete the floor
