Entering the Apartment Building

Learn how to enter the apartment building as Judas in The Binding of Isaac. This guide covers strategies, tips, and item interactions for this challenging character.

Walkthrough
  1. 1
    Judas begins with 1 Red Heart container, 3 coins, and The Book of Belial.
  2. 2
    He has a base 1.35x damage multiplier, which is further enhanced by The Book of Belial.
  3. 3
    Prioritize finding health upgrades due to his low starting health.
  4. 4
    Be cautious with Devil Deals, as they can be risky given his limited health.
  5. 5
    The Book of Belial can guarantee a Devil or Angel Room after a boss fight (in Rebirth) or increase the chance by 12.5% (in later DLCs).
Tips
  • Keep The Book of Belial if possible, especially early on, to maximize damage output.
  • Items that activate on low health, such as Scapular or Whore of Babylon, are easily triggered with Judas.
  • Dead Cat is a good early pickup as it effectively grants extra lives with only one starting Red Heart.
  • Black Judas, a form achieved by dying with Judas' Shadow, has a 2x damage multiplier and 1.1 base speed, with unique interactions regarding Red Heart containers in different DLCs.
  • Birthright transforms The Book of Belial into a passive item that scales its damage boost with the charges of the active item above it.
Unlocking Judas requires beating Satan for the first time. His unique starting item is The Book of Belial.
