Binding of Isaac: Rebirth Wiki

Added in Repentance

Clear Rune is an unlockable activated item added in The Binding of Isaac: Repentance.


Recharge time[]

This is a list of the following recharge times the item can have, depending on the consumable it mimicked last:


  • Book of Virtues Book of Virtues: Spawns purple-glowing rune wisps on the middle ring. The wisps spawn Runes/Soul Stones when destroyed, and enemies killed by the wisps' tears have a 15% chance to drop a Rune/Soul Stone. The effect of the wisps and the types of runes they spawn are independent from Clear Rune's charge time and the most recently used rune.
  • Butter! Butter!: Because Clear Rune is dropped upon usage, the recharge time for them is reset to 4, allowing to use more expensive runes much more frequently.
  • Car Battery Car Battery: Essentially uses the rune or soul stone twice.
  • Rune of Jera Rune of Jera: Allows Isaac to copy pickups with every use. This combination can double Lil' Battery Lil' Batteries, which can both circumvent the rune's high charge time and allow for game-breaking combos with repeated use of the synergy.


  • Tarot Cloth Tarot Cloth: No effect.
  • Void Void: If Void absorbs both Clear Rune and a consumable-producing item like Mom's Bottle of Pills Mom's Bottle of Pills the latter takes effect first, shifting any rune you are holding out of the primary consumable slot and rendering the Clear Rune effect useless.

In-game Footage[]


  • Despite being introduced in the Repentance DLC, Clear Rune's place in the Collection Menu is on Page 3, along with other Rebirth items. This is due to the item taking up a previously unused item id.
