Cold Orb

EP Cost: 9

You create a 1-foot diameter flying orb of dense, cold air on a point you can see within range. The orb is a tiny, fast-moving object with an AC of 18 and 30 hit points. Anytime a creature starts its turn within 40 ft. of the orb it must make a Constitution save. On a failed save it takes 4d6 cold damage and its movement speed is halved until the end of its next turn. On a successful save the creature takes half damage and suffers no movement penalty. Each round for the duration, you may use your bonus action to move the orb with a fly speed of 60 feet. Any exposed water that is within 40 ft. of the orb for a full minute turns to ice.
