Meat Cleaver - The Binding of Isaac

▾Table of Contents▾

Meat Cleaver is an unlockable active item in The Binding of Isaac, added in the Repentance DLC.

Splits each enemy into two smaller versions that have ~40% health each.

Normal enemies can be split up to 2 times, while champions and bosses up to 3 times. Attempting to split over the maximum allowed amount deals 25 damage to enemies instead.

Some enemies, such as Mr. Maw that has a cable holding the two parts, will be detached instead.

Cannot split invincible enemies, including Hosts while lowered.

Final bosses cannot be split.

Delirium has no limit on how many times it can split.

Some bosses have special behavior when split:
• Gemini will separate both of its pieces.
• Loki turns into Lokii.
• Chub / C.H.A.D. / Carrion Queen will instantly die.
• Gabriel / Uriel will make each copy spawn a Key Piece.
• Horny Boys will turn into Loki and Hornfel.
