Psychological Tension System — Judas Guide

Unlock the secrets of Judas' Psychological Tension System in The Binding of Isaac. Learn how to manage his low health, leverage The Book of Belial, and master Black Judas.

Walkthrough
  1. 1
    Judas' Starting Setup: Judas begins with 1 Red Heart container, 3 coins, and The Book of Belial. He also has a 1.35x damage multiplier.
  2. 2
    Black Judas: Upon dying with Judas' Shadow, you respawn as Black Judas. This form has 2 Black Hearts, a 2x damage multiplier, and 1.1 base speed. Black Judas has the highest damage multiplier among playable characters.
  3. 3
    Black Judas Health Mechanics: In Rebirth, Black Judas can gain Red Heart containers. However, in Repentance and Repentance+, Red Heart containers are converted to Black Hearts, and items granting Red Hearts will instead grant Black Hearts.
  4. 4
    Character Equivalence: Black Judas counts as Judas for achievements and unlocks, including Completion Marks. In Repentance, he also benefits from Tainted Judas' bonus effects when using Dark Arts.
Tips
  • The Book of Belial: This active item is crucial for Judas. Its damage increase is significant. In Rebirth, it guarantees a Devil or Angel Room after a boss. In other versions, it increases the chance by 12.5%.
  • Health Management: Due to Judas' low starting health, prioritize health upgrades. Devil Deals can be risky.
  • Low-Health Synergies: Items that activate on low health, like Scapular, Monkey Paw, Glyph of Balance, and Whore of Babylon, are easily triggered with Judas.
  • Dead Cat: This item has minimal downside for Judas early on, as he starts with only one Red Heart. It also contributes to the Guppy transformation.
Judas' reward is access to his unique playstyle, focusing on high damage output at the cost of survivability, and the potential to become the even more powerful Black Judas.
