Designed for less experienced DMs, this Pdf gives some advice on how to run underwater adventures.

Ok for the price, but if you (like myself) have run an extended underwater adventure (e.g. the Sahuagin-trilogy in AD&D), you probably won't need it.

My least favourite Indulgence so far.

This PDF nicely goes over some of the pitfalls players will have with underwater adventures. It gives some good ideas to overcome those issues and to get players interested in going into the depths. A few more mechanical or crunch ideas would have allowed me to give this product more stars, but if you are a DM who has run several underwater adventures then this product goes over what you have already learned. Unfortunately it does not give any exceptional new methods to handling all the pitfalls, but the layered idea is pretty nice. At one point the pdf says to not take away all the penalties of underwater adventures and a paragraph later it introduces masterwork armor that has no penalty to swim checks. =( For a buck fifty its a nice document for experienced DMs, but a really good document for less experienced DMs.

What the title says! A lot of this document is rather like an extended discussion on the standard underwater rules, their implications for characters and how to hook characters into an underwater adventure and make it as cool as possible. Unfortunately this section doesn't expand much on things ruleswise; as another reviewer says, the bends are mentioned but never explained, though I guess "If you surface without Deep Dive or similar protection you die" gives extra incentive to keep the mage alive and functioning and avoid dispels! Two new spells are introduced both of which are good utility spells, and the new monster is great and possibly the best thing in the pdf. So not a perfect product, but at $1.50, well worth the money.

First of all: A BUCK FIFTY!!

I found this pdf to be a useful supplement to the existing underwater rules, whether it is for an adventure or a few encounters. The monster presented, and it's sample use as a recurring villain, were imaginative. Environmental hazards, combat influences, and ways of overcoming them, were well presented.

My only negative: the hazards of pressure change and "the bends" are discussed, but not detailed in game terms. More crunch here would have been appreciated.

Another positive: the word "whingers" is used in the intro!
