Crystal Ball

Effects

Upon use, it:

• Reveals the floor layout and all special rooms except the Super Secret Room.
• Drops either a (Soul Heart) Soul Heart or a random card or rune. (50% chance of either)
• (Added in Repentance) While held, increases the chance of finding a Planetarium by 15%, or 100% if a treasure room has been skipped.

Notes

• The map revealing effect will not work if the Curse of the Lost is active.
• It's possible to get more than one Crystal Ball from Fortune Tellers on a single run.
• (Added in Repentance) The Planetarium bonus guarantees the level generation to attempt placing one, but the level layout may not have enough room. Read the article on (Planetarium) Planetariums for further details.

Synergies

• (Added in Repentance) Book of Virtues: Wisps have much greater health than normal wisps. Tears that are fired from the wisps will auto aim towards nearby enemies, similar to Demon Baby.

Interactions

• (Daemon's Tail) Daemon's Tail: The chance to drop cards or runes will change to 90%/10% in favor of cards.
