All Deduction and Revelation of the Culprit Answers in Crimson Desert

With all culprits now spoken to, it's time to return to the Calphadean Defender, where you can answer the questions in the following order:

  1. The quartermaster and the merchant are suspicious.
  2. The workers and the blacksmith are working till dawn.
  3. Didn't look too happy with Caspar.
  4. The lad seemed much troubled, with all the iron coming from who knows where.
  5. The supplies they received were in poor condition.
  6. He seems to take pride in the things he crafts.

Answering correctly will allow the Calphadean Defender to deduce that Helmut, the Blacksmith, is the culprit. You're now tasked with traveling south, where you can confront Helmut, tie him up, and ride back to Calphade to deliver him to the guards for justice.
