Aquatic Dominion

Caster directly connects to the Plane of Water and forces the environment to become your domain. 150 ft in all directions of the caster now becomes covered by 40 ft deep water. During the casting process, you may choose to freeze the water beneath some allies or objects. All creatures that aren't standing on a higher surface must make a strength throw against the caster's spell DC+3 or be submerged 10 ft underwater at the start of their next turn. Flying creatures are unaffected so long as they are 40ft off the ground before the spell is cast. There is a 50% that a Water Weird from the plane of water is summoned and obeys you.
