Mom's Key

Effects

• Gives Isaac two (Key) Keys.
• If a non- (Red Chest) Red Chest spawns hearts, coins, bombs and/or keys, causes the chest to spawn a second group of said pickups, effectively doubling the average pickup yield.
• (Added in Afterbirth) This item belongs to the Yes Mother? set. Collecting three items from this set will transform Isaac into his mother.

Notes

• Mom's Key cannot change the contents of a chest; it will only cause it to spawn extra pickups.
• All other chest rewards (such as pills, cards, items, etc.) will not cause the chest to spawn additional pickups.
• (Added in Repentance) Does not affect (Old Chest) Old Chests.

Interactions

• Mom's Key: Does not further increase the amount of pickups spawned when multiple copies of the item are acquired.
