The Ruin Mask in The Division 2 appears to come from the secret hunter in the Mutiny Climax Mission on Master difficulty ; community guides say you need to trigger the hunter encounter and then kill him to get the mask drop.

What players are saying

  • One guide says the mission is United Iron Works / Mr. Anderson’s Climax Mission on Master and that the Ruin Mask drops after defeating the secret hunter boss.
  • Another source describes the same reward as coming from eliminating the secret hunter Sgt. Gunnar in the Mutiny Climax Mission on Master.
  • Reddit posts from March 2026 suggest there was still debate about the exact legit method, but players repeatedly pointed to the same Master-difficulty hunter reward path.

Practical route

  1. Unlock and enter the Mutiny Climax Mission on Master difficulty.
  1. Follow the mission steps needed to spawn the secret hunter encounter.
  1. Defeat the hunter within the encounter window, then collect the Ruin Mask drop.

Notes

  • Some guides mention a workaround involving Turmoil and ricochet damage through glass to trigger the encounter more easily.
  • Community posts also suggest the method may have changed over time, so newer patches may affect the exact trigger steps.
