Binding of Isaac: Rebirth Wiki

(except in Rebirth)

For all Tech items, check Tech (disambiguation)

Tech X is a passive item added in The Binding of Isaac: Afterbirth.

Effects[ | ]

  • Isaac's tears are replaced with ring-shaped lasers.
    • Shots can be charged to increase the size of the rings.
    • The rings deal damage 15 times per second. Only the outer circumference of the rings will deal damage.
    • Rings pass through obstacles and enemies. Rings have infinite range and will travel until they hit a wall.
    • (in Repentance) Damage dealt is based on the amount charged, starting at around 25% Isaac's damage and approaches 100% at maximum charge.
      • At 30.00 fire rate or above (0 tear delay or lower), charging is no longer needed and fires 30 rings per second. Higher fire rate results in higher laser damage.
        • Damage per Tick is capped at 100% Isaac's Damage, at 90.00 fire rate.

Notes[ | ]

  • The rings are similar in appearance to the combination of Collectible The Ludovico Technique iconThe Ludovico Technique and Collectible Technology iconTechnology.
  • The laser rings will linger for a brief moment upon touching a wall, allowing more damage to be dealt to enemies closer to walls.
  • The "R U A WIZARD?" pill effect does not work with Tech X.
  • Acquiring an extra copy of Tech X will shoot an extra laser ring.
  • (except in Repentance) Charging only increases size, not damage. It is useful for hard-to-hit enemies or hitting a wide area at once, but spamming small, uncharged shots will lead to much higher damage output.
    • (in Afterbirth †) With the charge bars option enabled, the rings can be released immediately as the charge bar appears for easier gauging of maximum damage output.
  • (in Repentance) The maximum ring size is slightly smaller in Repentance.
