Use the harpoon rowboat to climb Ancient Spire Outpost. I did this the other day just for fun and am slightly surprised to see it isn't a category yet.

Rules:

• Rowboat must start in the ocean
• Run starts when harpoon is fired the first time
• Run ends when the harpoon is attached to the outside wall of the tavern and the rowboat has been reeled all the way in
• Player must be manning the harpoon gun at all times, no hopping off to push the rowboat
• Crew size 1
• No other players may assist by pushing the rowboat, throwing blunderbombs, or any other means of assistance
