Along with a plea to keep water as water and not ice, I have a few water-centric spell ideas. I don't have fancy names or descriptions, just ideas of what the effects would be.
- Something to help with swimming.
- Something to help keep the rain off you (it's stormy here at the University!)
- A way to un-drench yourself with hydromancy as well as aeromancy. (again with the storms!)
- A wall or stationary wave of water to make it harder for enemies to get close enough to attack you, and maybe deflect some projectiles. Approaching enemies could have a chance to get knocked over when trying to push through it.
- A swirling column of water to keep enemies spinning and out of commission a while, and maybe make them dizzy and nauseous!
