What this background is good for

Choose Mariner if you want a character who turns dockside fights, crew loyalty, smuggling, storm survival, and navigation challenges into usable table momentum. Its skill package points toward Athletics and Perception, so the background naturally rewards players who ask questions, notice patterns, and act on practical details. As a Maritime background, it gives the character a clear place in the world instead of just a mechanical bonus. The Alert feat, Navigator's Tools, and Strength, Dexterity, and Wisdom abilities help define how this character contributes before initiative is rolled.
