Fortune Cookie

Effects

Gives Isaac a fortune, Soul Heart, Card, Rune, or trinket, similar to a Fortune Telling Machine. Fortunes are much more likely to be given than anything else.

Loot Table | Pickup | Chance | | --- | --- | | Fortune | 69.5% | | Soul Heart | 15% | | Card or Rune | 12% | | Trinket | 3.5% |

Ironically, this item is unaffected by Luck.
On its own, this item is considerably worse at generating Cards, Runes, and Soul Hearts than Crystal Ball; Fortune Cookie produces 1 of either per 7.4 charges on average, while Crystal Ball produces 1 per 6 charges guaranteed. However, with 9 Volt, Fortune Cookie produces 1 per 3.7 charges on average, nearly twice as often as Crystal Ball.
(Dice Shard) Dice Shard, (Emergency Contact) Emergency Contact, and (Cracked Key) Cracked Key can be generated by this item.

Book of Virtues: Spawns a green wisp on the middle ring. Each wisp gives Isaac +0.2 Luck. If wisps are lost, Luck is only updated after Isaac's Luck changes through any means (this is most likely a bug; see bugs section of Book of Virtues). This mechanic also causes the first wisp given to not increase Luck.
