A Guide to Running Underwater Campaigns

Underwater Campaigns is the perfect resource for exploring the wonder and danger of underwater worlds and adventure - oceans, lakes, rivers, sewers, and flooded ruins. Whether you want to add an aquatic room in your dungeon, flesh out trade with the ocean creatures, or create an epic tale at 20,000 feet, this work is for you! This work takes existing nature and weaves the fantasy setting through it while guiding you to create your own underwater campaigns.

Inside, you will find:

- An underwater adventure seed for any level

- 68 random underwater encounters

- Underwater rules for combat, skills, feats, and magic

- 67 new aquatic monsters

- The return of the Colossal creature size!

- 26 new aquatic NPCs

- The return of the Gehreleths!

- 35 spells to help or hinder underwater targets

- 19 magic items for underwater adventuring

- New disease mechanics and examples

- 2 unique underwater locations

- Professional layout using over 100 pictures on 166 pages

We are honored and delighted that Underwater Campaigns was noticed and mentioned by WoTC

Keep the error finding coming! I have a thick skin and yeah any work of this size is going to have some weirdness. I have about 3 pages of notes for the 1.1 version. We will release the updated version once we break even (hit the silver medal). I'm thinking this will be in about 3 weeks. this gives me (and you :)) time to find more bugs that I can squash. And thank you. Seriously.

yeah we blasted it on Social Media. It is an interesting take on the review process. I think I like it. Its like watching someone discover my work for the first time and sort of "mutter aloud about whether they like it or not." Dig the approach.

Thanks! Glad you enjoyed it. Yeah, I do full book reviews as well sometimes, but I wanted to do a series that helps people find titles after they move off of the front page of the site. It's really hard to find what you are looking for by just browsing, so I'm hoping people will stumble upon titles by watching the series over time as well.

I'm one of the "old and crusties" from the early 80s so I do most of my communication on Facebook and Instagram. I have had very spotty issues with Discord of late and have all but abandoned it. I do have a linktree though and that shows the best ways to communicate with me :) I hope this helps.

Rules Edition(s)
Original electronic
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.
