Your powers rise like the tides.
Associated Bloodline: Aquatic [APG].
When you are in a body of water large enough to float in, your effective caster level is increased by 1.
You prefer to attack with water rather than to leech it away.
Water Blast (Sp): At 1st level, as a standard action, you can fire a bolt of water at a foe within 30 feet as a ranged touch attack. The foe is knocked prone, and at your option may be pushed 5 feet directly away from you. A reflex save (DC 10 +1/2 your sorcerer level + your Charisma modifier) negates this effect. You can use this ability a number of times per day equal to 3 + your Charisma modifier.
This bloodline power replaces dehydrating touch.
