Welcome to The Beggars Appreciation Group where we appreciate the help of beggars

Beggars are an NPC from The Binding Of Isaac that well..... beg

Bumping into The Beggar gives him a penny, and he has a chance of dropping a random pickup, a trinket, an item or nothing at all. This can be repeated until he drops an item, after which he will vanish. The Beggar will remain in the room until he drops an item or is blown up by a bomb.

If blown up, he will drop a couple of random consumable items. He always gives a pickup or an item if he doesn't drop anything after giving him 4 cents.

The Beggar's final reward can be a hp up or any item you could get from an item room.
Items from The Beggar are usually cheaper than the items from the shop.
It also seems that giving a beggar your last cent (ie. dropping you to 0 cents) has a higher chance of an item dropping.
Blowing up a Beggar increases the chances of finding the Devil Room.
Giving the Beggar coins increases the chance of finding the Angel Room.
The Tarot Card XX Judgement can be used to spawn a Beggar in any room.

This causes the beggar to drop items appropriate to that room, allowing a player to get free devil room items or multiple cubes of meat, for example

This is why the beggar has such an important role in the game.
