Beggar

Beggars are a group of randomly occurring NPCs in the game. There are a total of 8 types of beggars, each requesting different donations. Isaac can donate pennies, keys, hearts, or bombs by simply walking into them. With each donation, the beggar has a chance to drop various pickups and trinkets. Sometimes, the beggar will drop an item and disappear. The rate of drops isn't influenced by luck.

Beggars can be destroyed by bombs, causing them to drop a few pickups. If destroyed in The Chest or Dark Room they will drop an item, with the exception of the Shell Game who still drops pickups.

Normal Beggars, Devil Beggars, Key Masters, and Bomb Bums can be spawned using XX - Judgement.

Beggar

Beggars ask for coins. Each coin donated has a chance to have him drop a random pickup, card, or a pedestal item. After spawning a pedestal item, the Beggar will disappear and can no longer be donated to.

When spawning a pedestal item, beggars have:

• a 50% chance to spawn one of the following hard-coded items:
  • Lunch
  • Dinner
  • Dessert
  • Breakfast
  • Rotten Meat
• a 50% chance to spawn an item from the Beggar item pool.

The hard-coded items can be spawned if encountered or even collected before during the run.

Notes

• Bombing a normal Beggar increases the chance for the Angel/Devil Room to open for the floor by 35%, and donating to a normal Beggar until it spawns an item increases the chance to get an Angel Room for the floor.

Devil Beggar

Devil Beggars ask for hearts. Each heart donated has a chance to have him drop a card, pill, trinket, or an item from the Devil Beggar item pool. After spawning a pedestal item, the beggar will disappear and can no longer be donated to.

Notes

• Bombing a Devil Beggar increases the chance to get an Angel Room for the floor and donating to a Devil Beggar until it spawns an item decreases the chance to get an Angel Room for the floor.
• Similar to a Blood Donation Machine, Devil Beggars will take Eternal Hearts first, then Red Hearts. If Isaac only has half a Red Heart remaining, he will then take Black Hearts and Soul Hearts. It is possible to die in this manner.
  • Devil Beggars ignore eternal hearts when taking hearts.
• Until The Womb/Utero floors, the donation will only be 1/2 a heart. Once Isaac reaches chapter 4, it will be a whole heart. This can be mitigated by The Wafer, Cancer or Percs, which cuts it back down to 1/2 heart.
• The donations activate damage effects, such as Holy Water or Celtic Cross.
• Activating Devil Beggars while using an item that grants invincibility, such as the Book of Shadows or Rune of Algiz, will not lower Isaac's health, but will still cause the beggar to spawn items. Holy Mantle is ignored, though, so The Lost will be killed instantly.
  • It is possible to exploit the invincibility frames after taking damage to donate twice for the price of one donation. Blind Rage doubles the invincibility frames, thus allowing to activate the Devil Beggar even more times in that period.
  • Bone Hearts will not be broken by donating to a Devil Beggar, and can drain multiple Bone Hearts without breaking them.
• Devil Beggars always drop Spiders when killed by a bomb.
• If the player has Soul Hearts, Black Hearts or Eternal Hearts along with Red Heart Containers, it is possible to donate Red Hearts until all Red Heart Containers are empty and not die in the result.

Key Master

Key Masters are rare and ask for keys. Each key donated has a chance to have him drop a random chest, an item from the Key Master item pool, or the Paper Clip. After spawning a pedestal item or the Paper Clip, the Key Master will disappear and can no longer be donated to.

Notes

• If found inside the Secret Room on Dark Room or The Chest, the chest payouts will contain items.
• Possessing a Golden Key will not affect the Key Master in any way.

Bomb Bum

Bomb Bums are extremely rare and ask for bombs. Each bomb donated has a chance to have him drop 1-2 Bombs or an item from the Bomb Bum item pool. After spawning a pedestal item, the bomb bum will disappear and can no longer be donated to.

Bomb Bums are much more common and give 1-3 coins instead of bombs.

Notes

• It is possible that the Bomb Bum will spawn a Troll Bomb underneath itself.
• Possessing a Golden Bomb will not affect the Bomb Bum in any way.
• Bomb Bums are not only immune to bombs, but they will respond to an attempt to destroy them by spawning several troll bombs like XVI - The Tower.
  • Bomb Bum can still be destroyed by certain types of explosions:
    • The exploding damage from the death of Dark Esau
    • The shockwave from Mama Mega!
  • Having Safety Scissors allows the player to acquire infinite bombs by bombing the beggar repeatedly.

Battery Bum

Battery Bums ask for coins. Each coin donated has a chance to give 1 to 3 charges on your active item, these charges can go above the charge cap, being full up to a maximum of two full charges. On top of that Battery Bums have chances to drop a Micro Battery, a Lil Battery, a Watch Battery, a AAA Battery, or a pedestal item.

When spawning a pedestal item, battery bums have a chance to spawn one of the following item :

9 Volt

• The Battery
• Sharp Plug
• Car Battery
• Charged Baby
• Jacob's Ladder
• Jumper Cables
• Glaucoma
• 4.5 Volt
• 120 Volt
• Battery Pack

Has a chance to drop random pickups, a pill or a trinket when blown up.

Notes

• Bombing a Battery Bum increases the chance for the Angel/Devil Room to open for the floor by 35%.

Rotten Beggar

Rotten Beggars ask for coins. Each coin donated has a chance to have him spawn blue flies, blue spiders, drop a Bone Heart, a Rotten Heart, the Fish Head, Fish Tail, Rotten Penny and Bob's Bladder trinkets, a pedestal item, or fart. After spawning a pedestal item, the Beggar will disappear and can no longer be donated to.

When spawning a pedestal item, rotten beggars have a chance to spawn one of the following items:

• Rotten Baby
• Rotten Meat
• Dead Onion
• Bob's Brain
• Bob's Curse
• Bob's Rotten Head
• Compost
• Rotten Tomato

Has a chance to drop Rotten Hearts when blown up, as well as spawning small maggots.

Shell Game

The Shell Game beggar can sometimes be found in the Arcade; he also has a very small chance to spawn elsewhere. After giving him a coin by bumping into him, he will lift a skull, revealing a Penny, Bomb, Red Heart, or Key. He will shuffle the skulls around and wait for Isaac to bump into 1 of the 3 shells. In return, he will either spawn 2 of the pickups or an Attack Fly.

Notes

• The shell chosen is irrelevant; possession of a Lucky Foot increases chances of winning.
• Sometimes, the item under the skulls will be the Skatole item. If this item is received, the Shell Game beggar will disappear. This is the only collectible item he can drop.
  • If Skatole has already been acquired, other Shell Game beggars will never give a second Skatole and will remain until destroyed.
  • If you wish to avoid a Skatole pickup (for example, you want to spend more coins before possibly acquiring Skatole), leave the room - this resets the Shell Game (though your previous coin is lost).
• An Arcade with a Blood Donation Machine and a Shell Game can provide the player with a large amount of resources. Donate the hearts that the beggar drops to the machine and use the coins to keep playing.
• Item payouts are subjected to the same spawning chances as usual. Bombs can be replaced with Troll Bombs or Double Bombs, Red Hearts can be replaced with Half Red Hearts, Soul Hearts, Black Hearts, Eternal Hearts, or Bone Hearts, and Pennies can be replaced with Nickels or Dimes. Under the effects of Humbling Bundle, bombs will be Double Bombs, Red Hearts will be Double Hearts, and Keys will be Key Rings.

Hell Game

The Hell Game beggar works the same way as the Shell Game beggar, except half of a heart is required to play. After paying him by bumping into him, he will lift a skull, revealing a Penny, Bomb, Black Heart, Key, or Card. He will then shuffle the skulls around and wait for Isaac to bump into one of them. In return, he will either spawn 2 of the shown pickups or a Spider.

Notes

• The shell chosen is irrelevant; possession of a Lucky Foot increases chances of winning.
• Sometimes, the item under the skull will be one from the Devil Room Item Pool. If it is recieved, the beggar will disappear.
• Unlike the devil beggar, bombing a Hell Game beggar does not affect the chance for an angel room to appear. Like the devil beggar, however, it will spawn spiders.
