In Repentance Added in Repentance[]



  • This item is a reference to Markus "Notch" Persson, the creator of Minecraft.
    • It resembles an Iron Pickaxe, which can be used to mine stones and ores.
    • The item durability being 64 could also be a reference the max amount of copies you could hold in a slot for most items in Minecraft.
  • The item is also a reference to the Notched Pickaxe from The Elder Scrolls V: Skyrim, which itself was most likely also a reference to Notch.
  • This item got significantly buffed from the original Binding of Isaac, where it could not open up secret rooms and could only break 1 rock for every use, though it did only have a 1 room recharge time.
  • Added in Repentance The "mineral" wisps that appear when using Book of Virtues Book of Virtues with this item follow the same scheme as they do in Minecraft, giving the player black, silver, gold, blue, and red wisps, most likely corresponding to the Minecraft minerals coal, iron, gold, diamond, and redstone respectively.
  • Added in Repentance The new effect from The Book of Belial The Book of Belial resembles an enchanted pickaxe that appears to have the following Minecraft enchantments: Efficiency (quicker usage), Fire Aspect (setting enemies on fire), Fortune (increased amount of drops when destroying obstacles), Knockback (increased knockback) and Unbreaking (increased durability).
    • The synergy as a whole references the fact that enchanted books are used to augment tools in Minecraft.
  • Using Iron Bar Iron Bar to repair the item is another reference to Minecraft where you can repair Iron Pickaxes using iron and an Anvil.
