From publisher blurb:
ADMIRAL o' the HIGH SEAS - naval combat supplement for use with the world's most popular roleplaying games.
For centuries, the boldest adventurers of all were sailors. If you want adventure, why limit yourself to dry land and dungeons when you can crew a tall ship and set sail for the end of the world?
Produced with the support of dozens of Kickstarter backers, this books contains rules for conducting naval battles and boarding actions, owning and operating a ship, exploring uncharted seas, and battling beasts of the deep. Design your own vessel, or choose from over twenty cutters, galleons, frgiates, and airships that any band of heroes would love to have, whatever their mission.
Run a blockade. Hunt a sea dragon. Capture a zeppelin. Become a pirate (just not of this book).
You've got a magic sword? That's great. I've got 80 canons and an iron-plated hull. Good luck stabbing that.
For use with PATHFINDER RPG and DUNGEONS & DRAGONS 4th EDITION.
Ideally suited to accompany the ZEITGEIST: The Gears of Revolution adventure path, Paizo's Skull & Shackles adventure path, or any seafaring campaign of your own devising.
