The Treasure of One-Armed Jack is a pirate treasure hunt inspired by 1980s movie Goonies and the book Treasure Island by Robert Louis Stevenson. A treasure map leads to Jolly Roger Isle, the location of a hidden treasure belonging to the legendary pirate, One-Armed Jack. However, the characters aren't the only ones after this pirate treasure; a red dragon covets it for her hoard.
If the characters manage to survive, they will end up with not just a large treasure, but also their own ship, Captain Jack's old sloop. This nautical adventure is a great starting off point for a seafaring campaign.
This adventure is optimized for 4 characters at 6th level. However, it includes adjusted information levels 4-8. It includes 4 maps, 8 unique treasure items, and 5 new variations of existing monsters.
