Land Lover

You are not comfortable on the open sea. While aboard a ship outside the view of land, you experience disadvantage on attack rolls, saves and ability checks requiring concentration or skill. You also must make a constitution save, DC 13 each day to avoid being nauseated. Once nauseated, you remain so until finishing a long rest.

FLAW. This is a flaw feat. At your DM's discretion, you may take this feat at level 1. If you do, you may also gain a feat, or increase two of ability scores by +1 (or one by +2).
