Heresy Act

Overview

Heresy Act refers to the acts of Episode: Heresy. Act 2 and Act 3 are where Barrow-Dyad catalysts became available.

Barrow-Dyad catalysts

• High-Impact Reserves (Act 2): Complete an Expert Court of Blades run with Barrow-Dyad equipped to start the quest A Needle's Path, then finish it with a second Expert run using a long-range loadout (Scout Rifles, Linear Fusion Rifles or Sniper Rifles).
• Hatchling: Starts from the quest A Hammer's Path in The Nether. The guide used does not state which act it belongs to.
• One for All (Act 3): Unlocked with the Sunless Cell strike in the third act. Completing the strike with Barrow-Dyad equipped starts A Hundredfold Path, which asks you to collect ten Tithing Wormspawn aboard the Dreadnaught.
• Target Lock: Starts from the quest A Silken Path in The Nether. The guide used does not state which act it belongs to.

The catalyst steps come from an April 2025 guide and may have changed since.
