Mom's Razor is a passive item added in The Binding of Isaac: Afterbirth †.

Effects[ | ]

  • Grants a razor familiar that orbits Isaac. Enemies that touch the razor take damage equal to 20% of Isaac's tear damage per tick or 300% of Isaac's damage per second ((in Repentance) 150% of Isaac's damage per second) and start to bleed.
    • (except in Repentance) Bleeding enemies take damage equal to 10% of their maximum health every 5 seconds. Bosses cannot bleed and won't take any damage from the razor.
    • (in Repentance) Bleeding enemies take damage based on how quickly they move; the faster the enemy, the more damage they take. While moving, a bleeding enemy leaves behind red creep that can damage other enemies. Bosses can bleed as well.
    • (except in Repentance) The razor does not block enemy shots.
    • (in Repentance) The razor blocks enemy shots.
  • This item belongs to the Yes Mother?Yes Mother? set. Collecting three items from this set will transform Isaac into his mother.

Notes[ | ]

  • (except in Repentance)It may not always be a good idea to take Mom's Razor if Isaac has one or more Pretty Flies as orbitals, as Mom's Razor can override Pretty Flies without giving protection from enemy shots.

Synergies[ | ]
