Ball of Shivering

This ball of water is thrown at a creature. The user makes a ranged attack roll (20/40), and on impact the ball hits the creature and bursts, covering them in water.

At the start of their next turn, the wet creature begins to shiver uncontrollably, and must pass a DC 13 Constitution saving throw or suffer 2d6 cold damage, half as much on a success, and they now move at half movement for the remainder of their turn, and have disadvantage on Dexterity saving throws. Those that pass the save do not suffer these effects. Creature returns to normal at the start of their next turn.

Notes: Speed Reduction: Impose, Disadvantage: Dexterity Saving Throws, Damage: Cold, Consumable
