This title is included in Undersea Sourcebook: Race & Class Guide

We'll be sunsetting this title to integrate it into Undersea Sourcebook: Race & Class Guide. The title is still available, as a legacy price, for now.

The Undersea Sourcebook series provides players and Dungeon Masters with everything they need to explore the crashing waves and the vast ocean depths below. 

Mutants & Mariners includes a host of new options for your ocean and undersea campaigns:

  • The infamous Pirate Class
  • Privateer and Smuggler pirate archetypes
  • College of Shanties — a piratical Bardic College (Yo ho ho!)
  • The Mutant, a new hybrid race compatible with existing races. Now you can play an elf-turtle, a rat-halfling, or a platypus half-orc... anything you can dream of.
  • Over 35 base mutations, including dolphins, sharks, quippers, bats, umber-hulks, armadillos, rhinos, and more.

This title is compatible with the Open Game License.

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
