Aquatic Grasp

Summon forth a number of vine-like water constructs that obey your will and move with you. Summon 1d4 + 4 magically infused liquid tendrils in a 5 foot radius around you. Each aquatic tendril has hit points equal to half of the caster's hit points rounded down and has a 30 foot melee reach.

As an action, you may either attempt a grapple or a ranged spell attack with each arm. To grapple, roll to hit and add your spellcasting modifier to the attack. An opponent can attempt to break free of the grapple at the end of its turn, each tendril has a Strength equal to 15 + spellcasting ability modifier.

If cast in large bodies of water the number of summoned arms is doubled.
