Alternatively, as an item, to be a counterweight to the Pills/Manual of Water Breathing and Barrel of Air. Downside: the affected units would have to stay within range of the holding commander. (see above) Second downside: what happens when an enemy (non-amphib) unit gets within range (for something the effect of the Barrel that's a 25-square sector) and is now surrounded by a "walking" wall of water? You see the problem (and I just thought of it while I was typing this!) Implemented badly, this could be hideously overpowered.

Why couldn't this just be the same as pills of air breathing and barrel of air? They don't cause ocean breathers to sufficate underwaater
