Poseidon's water-based abilities range from his passive wave-riding movement ability, Changing Tides, to his ultimate, Release the Kraken. Poseidon controls the battle field by slowing or impairing enemy movements. Besides dealing massive damage, his ultimate slows enemies in the blast radius, and his Whirlpool ability draws all enemies in the area toward the center of a raging maelstrom. Those players who enjoy playing support roles will definitely want to give this god a try tomorrow.
