Hello everyone. This is the third and final part in my three part series on underwater adventures. You may want to read my last two before moving on to today's article, which deals with fully aquatic adventures.
Wholly Aquatic Games
      
               In a wholly aquatic game the PCs should never see  dry land; they spend all of their time underwater and are most likely members  of an aquatic race themselves.  Games  like this are best run from the get-go with a campaign focusing on underwater  life and adventure, as they typically require that the PCs belong to an aquatic  race (you’ll probably want to set the starting level slightly higher than  normal so that players who want to do so can choose to be a slightly more  interesting or powerful race such as a sahuagin or a locathah. Alternatively,  you could just have them choose races normally and then swap out their lungs  for gills, no mechanical adjustment necessary).
      
               It is possible to move an existing game to become  wholly aquatic, but this can be a tricky endeavor. If your PCs are of a high  enough level that something like surviving a few thousand leagues under the sea  isn’t a major problem for them (perhaps they no longer need to breathe? Last  time I checked there weren’t any comprehensive rules for surviving the pressure  of deep sea diving) then the only obstacle between you and oceanic adventures  is making sure that the action is going on underwater. This can be difficult,  as most PCs tend to think that whatever happens below the waves stays below the  waves, but there are a few ways to do it. If your party answers to any kind of  authority figure (especially a religious or political one) they might be told  that trouble is brewing at the bottom of the ocean and they are needed to sort  out the conflict, whether that means working out a treaty between the Sahuagin  and the Tritons or finding Cthulhu and banishing him before he awakens. If your  PCs are too low-level (or just plain not clever enough) to surmount the  problems the water provides, you may need to give them a hand, either by  providing them with magical amulets of “Oh, we can breathe underwater now” or  by other means. Air-bubble cities at the bottom of the ocean theoretically go a  long way to solve the problem, but any time spent in those cities isn’t really “underwater”  and so they won’t feel especially different.
      
               Which brings me to the most important part of an  aquatic game (whole, mostly, or partially): use what you have! Scenery is  great, and finally getting a chance to use cool monsters like dire sharks and  krakens is fun too, but if you really want your aquatic adventure to feel  different from other adventures make good use of the terrain. What does that  mean? 3-D fights, for one. Currents might also make fun terrain features, as  might magical patches of boiling or freezing (even frozen?) water.
      
Below is a campaign idea for a wholly aquatic  game.  
      
The Great Hunt
      
               This campaign is designed to be about community and  a gritty struggle for survival.  The PCs  all play aquatic characters (being of the same race works well but is not required)  from the same tribe (or community, or kingdom, or what have you).  Their world is defined by two major aspects:  war with other factions (rival tribes, upstart warlords, angry storm giants,  etc.), and the constant hunt for resources.   During the campaign the PCs’ primary goal should be to secure resources  (particularly food) to support their tribe.  As a result, most of their adventures should  involve the hunting of giant aquatic beasts, for no other reason than to feed  their people.  Raiding other tribal  territories is another good way to stock up on food and raw materials.  Other campaign goals should include things  like establishing a strong protected territory where the PCs’ tribe can thrive  and dealing with potentially dangerous threats like sea-going dragons, and  swarms of sahuagin.  A good way to  develop the campaign is to have the PCs’ triumphs lead to greater influence for  them and their tribe, perhaps managing to end centuries of war by uniting all  the opposing factions, or building up a force large enough to rule unchallenged  for generations.  
      
All right, folks, that’s it for this week’s Grave Plots. Until next time, I wish you all the best in your gaming endeavors.
