“Mer” man in an underwater oxygen rich atmosphere inside a water-tight sphere.

In the game we’re developing, the Mer are a race of aquatic Elvish with extra chambers in their lungs, the ability to stay underwater for up to an hour, and a gland in their foreheads similar to what dolphin’s have, which gives them the ability to stun their enemies. This ability takes a long time and a lot of practice before it could be abused in combat situations, it would be much better as a defensive weapon than an offensive one. This scene is supposed to be inside an oxygen rich spherical bubble underwater.  ~~~TaleRocker
