Quick answer

Eredrim Location & Counter Build

Reach the lower Citadel of Penance arena, defeat The Warden, and interact with Eredrim's body. Community testing pairs the Shell's counter-focused role with Great Martyr's Blade and Frost; Patch 1 separately increased the blade's attack damage by 20%.

Route

What to do

  1. 1Reach the lower Citadel of Penance arena.
  2. 2Defeat The Warden encounter guarding the route.
  3. 3Interact with the body after the fight to claim Eredrim.
  4. 4Check the current platform patch before comparing the Great Martyr's Blade setup.

Counter-focused identity

Eredrim's current role evidence is more specific than a generic tank label. The cited NG++ test describes a high-execution counter build using Great Martyr's Blade and Frost support. Its value therefore depends on timing and setup rather than only raw survivability.

This makes Eredrim suitable for players who want deliberate boss-control windows and are comfortable with a slower heavy-weapon rhythm. It is less useful as a blind recommendation for someone seeking fast exploration clear.

Reading the Patch 1 buff

Balance Patch 1 increased Great Martyr's Blade attack damage by 20%. That exact change is strong evidence that the weapon improved, but it does not prove a post-patch S tier or produce a new DPS total without the underlying formula and current stats.

Use the patch note as an update flag: retest the pairing in your current version and keep execution cost, Frost support, and unlock timing visible beside the buff.
