Marine

Note: Encounters while traveling on a ship or boat can be very exciting but also potentially very dangerous. If a monster were to pull a heavily armored fighter into the water he would be in dire danger of dying a very unheroic death. PC's traveling on-board a ship or boat should plan their spells and equipment carefully before beginning such a journey in order to be able to respond most effectively to encounters sure to come.

Description: The following events are applicable if the PC's are traveling on a ship or boat for an extended duration.

Recommended Frequency: One time every two hours, whenever PC's travel more than 10 minutes, or whenever the GM desires.
