Naval Chase Complications

d20	Complication
1	Your ship finds itself in the path of a small whirlpool. Make a DC 15 Wisdom (Vehicles – Water) check to navigate the hazard. On a failed check you momentarily lose control of the ship. The ship’s speed is reduced to 0 ft. and the ship rotates 180° (must spend next action turning around instead of pursuing/running).
2	Your ship is hit hard by currents in all directions as the sea suddenly swells around you. Make a DC 10 Wisdom (Vehicles – Water) check to navigate through the swollen sea. On a failed save, your ship’s speed slows by half for one round.
3	Your ship finds itself traveling through thick seaweed. Make a DC 10 Wisdom (Nature) check. On a failed check, you are unable to find a clear path through the seaweed and your ship’s speed slows by 3 quarters for one round.
4	A sea monster joins the chase. Roll a random encounter (see page 118 of the DMG) or pick your own monster.
5	A coral reef blocks your path. Make a DC 10 Wisdom (Nature) check to find an alternate route. On a failed check, your ship’s speed slows by 3 quarters for one round, and your ship takes 4d10 slashing damage.
6	Jagged rocks block the path of the ship. Make a DC 10 Wisdom (Perception) check to find an alternate route. On failed check, you ship’s speed slows by 3 quarters for one round, and your ship takes 4d10 piercing damage.
7	A large swell or wave is headed your way. Make a DC 10 Intelligence (Vehicles – Water) check to successfully navigate the wave. On failed check, your ship’s speed slows by 3 quarters for one round and your ship takes 4d10 bludgeoning damage.
8	A sudden, massive gust of wind blows against the ship, regardless of the current wind direction. Make a DC 15 Wisdom (Vehicles – Water) check to maintain control of the ship. On a failed check, you momentarily lose control of the ship. The ship’s speed is reduced to 0 ft., and the ship rotates 180° (must spend next action turning around instead of pursuing/running). The wind direction quickly returns to normal.
9	The wind suddenly drops off, your speed is reduced by half, and you find yourself entering a dead calm. Make a DC 15 Wisdom (Survival) check to find the wind. On a failed check, your ship’s speed is reduced to 0 ft.
10	Patches of fog rise up out of the sea all around you. Make a DC 15 Wisdom (Survival) check to find a clear spot. On a failed check, your visibility is reduced to 200 ft.
