The Book of Sin is an unlockable activated item.

Effect

• Generates a random pickup, pill, card, or rune.
  • This includes Cracked Key, Dice Shard, and Emergency Contact.
  • Hearts can be of any type other than Blended Hearts.
  • Pennies can be of any type, with higher value coins and Lucky Pennies being rarer.
  • Bombs and Keys will always be singular (unless Isaac has Bogo Bombs and/or Humbling Bundle).
  • Batteries spawned can only be Lil' Batteries and, more rarely, a Mega Battery or Golden Battery. The Book of Sin cannot generate a Micro Battery.
• Each pickup seems to be equally likely, which means that there is around a 1/7 chance to get a particular type of pickup.
• This item belongs to the Bookworm set. Collecting three items from this set will transform Isaac into Bookworm.

Synergies

• Book of Virtues: Grants a random wisp based on one of the Seven Deadly Sins. The wisp spawned isn't linked to the pickup dropped.
  • Pride: a blue bomb wisp in the middle ring. When destroyed, a small homing bomb that deals normal troll bomb damage is spawned.
  • Greed: 3 yellow coin wisps in the outer ring. Their tears may petrify enemies like Midas' Touch.
  • Wrath: an orange bomb wisp in the middle ring, which fire flaming tears. They drop troll bombs when continuously firing, and leave a bomb pickup when they die.
  • Envy: a white face-like wisp in the outer ring.
  • Lust: a randomly colored pill wisp in the inner ring, with effects that are the same as Mom's Bottle of Pills wisps.
  • Gluttony: a heart wisp in the middle ring, with effects that are the same as Yum Heart wisps.
  • Sloth: a Bob's Head wisp in the middle ring. Their tears travel in an arc like Ipecac but don't always explode on impact. There is a small chance for an exploding tear.

Trivia

• The Book of Sin is a reference to the Seven Deadly Sins. Unlike other Book items, The Book of Sin doesn't appear to be based on a real book or scripture.
