You gain advantage on ability checks made using fishing tackle. If you have access to a body of water that sustains marine life, you can maintain moderate lifestyle while working as a fisher, and you can catch enough food to feed yourself and up to ten other people each day.
Fishing Tale
You can tell a compelling tale, whether tall or true, to impress and entertain others. Once a day, you can tell your story to willing listeners. At the DM's discretion, a number of those listeners become friendly toward you; this is not a magical effect, and continued amicability on their part depends on your actions. You can roll on a table provided in the Ghosts of Saltmarsh, page 29, to help determine the theme of your tale or choose one that best fits your character. Alternatively, work with your DM to create your own fishing tale.
