The Basement's Secrets — Judas Walkthrough

Unlock the secrets of The Basement with Judas! This guide details his starting stats, unique item, and strategies for survival and victory in The Binding of Isaac.

Walkthrough
  1. 1
    Judas is unlocked after defeating Satan for the first time.
  2. 2
    He begins with 1 Red Heart container, 3 coins, and the active item, The Book of Belial.
  3. 3
    Judas has a base damage multiplier of 1.35x.
  4. 4
    Upon death with Judas' Shadow, the player respawns as Black Judas (or Dark Judas).
  5. 5
    Black Judas starts with 2 Black Hearts, a 2x damage multiplier, and 1.1 base speed. He has the highest damage multiplier among playable characters.
  6. 6
    DLC specific: In Repentance and Repentance+, Black Judas cannot gain Red Heart containers; items that would grant them instead provide Black Hearts. In earlier versions, he could gain Red Hearts.
  7. 7
    Black Judas counts as Judas for achievements and unlocks, including Completion Marks.
  8. 8
    In Repentance and Repentance+, Black Judas gains Tainted Judas' bonus effects when using Dark Arts.
Tips
  • The Book of Belial's damage increase is significant; consider keeping it until other damage sources are acquired.
  • In Rebirth, The Book of Belial guarantees a Devil or Angel Room after a boss. In later DLCs, it increases the chance by 12.5%.
  • Prioritize health upgrades due to Judas' low starting health. Devil Deals can be risky.
  • Dead Cat is highly effective early on for Judas, as he starts with only one Red Heart. It also contributes to the Guppy transformation.
  • Items that activate at low health, such as Scapular, Monkey Paw, Glyph of Balance, and Whore of Babylon, are easily triggered with Judas.
  • Birthright (Repentance+) makes The Book of Belial a passive item that can be held under other active items, with its damage boost scaling with charges. This may not work with all item types.

Unlocking Judas requires beating Satan. Playing as Judas can lead to unlocking Tainted Judas (Repentance+) and various other character-specific achievements.
