Restless Sea

Rapid currents and quick trade routes make these waters popular with merchants, but only the bravest and most skilled sailors are willing to chance the frequent, dangerous, and unpredictable waves. Adventurers journeying through this region or along its coast have to overcome an unusually high number of weather event exploration challenges, as well as some combat encounters and social encounters.

Terrains. Coast, water.

Tiers. Regions with calm waters might be tier 1, but most adventurous seas are tier 2 or tier 3.

Weather. 1–7 clear, 8–11 overcast, 12–16 rain, 17–25 mist.

Journey Activities. Adventurers have disadvantage on checks made to Scout. Busking is possible on coastlines, but not the open sea. Checks made to Hide Tracks on the open sea automatically succeed, and those made to Track automatically fail. Checks to Hunt and Gather are made with advantage .

Rolling Mists. Adventurers gain an expertise die on Stealth checks if the weather is not clear.

Thick Fog. Without the sight of natural landmarks to guide them, adventurers have disadvantage on checks made to navigate the area if the weather is not clear.
