Tell Duke you won't go to the Tower of Gabnid five times. Each refusal must be in a different room and the Master's room will only count if you speak with him.
Upon returning from Dasdan Island, get to Chezni's home without engaging in battle with any of the Sgt Alons roaming around town. If you fail, leave town and come back.
While escaping Conshuito after rescuing Wind, don't speak with or kill any NPCs. This can only be done while freeing Wind before the party leaves town. Random encounters OK, reload if you fail.
