The bonus effects of water magic are too weak. Complete the list:

Fire: attack bonus
Air: accurasy bonus
Earth: armour bonus
Water: defence bonus
-------------

Currently water only gives a really puny ability of water breathing for 1 unit / power level. This is almost meaningless, and certainly not in par with the other bonus effects.

It would be neat to have the defence option anyway, and this would balance the water dragon with the fire dragon. Currently the fire dragon is a much fiercer beast because of the automatical attack bonus.

The water breathing could parhaps be changed so that any water mage can enter the sea, but not take anybody with him. It's not all that important.

Parhaps an air mage could exit the sea, if aquatic, to balance this.
