Success and Failure of Quest Steps

• Success Condition:
  The party succeeds at a quest step by completing that step’s quest encounter, as described in the quest step’s objective section. The specific instructions or choices for completing the step are found in the "Quest Objective" section of the quest step (page 47).

• Failure Condition:
  The party fails its quest step if it fails that step’s quest encounter, unless the quest step says otherwise. This applies regardless of whether the encounter is peaceful or a battle. The quest step will specify if a peaceful or battle encounter can be failed without the quest also failing (page 46).

Effects of Failing a Quest Step

• If the party fails its quest step:
  • The session ends.
  • The campaign ends.
  • See "Ending the Session" (page 48) and "Losing the Campaign" (page 50).

Summary

• Success: Complete the quest step’s encounter as described in the quest objective.
• Failure: Fail the quest step’s encounter (unless the step says otherwise).
• Consequence of Failure: Both the current session and the campaign end immediately.
