A Small, swirling cloud of ice and snow appears and hovers in an unoccupied space you can see within range. The cloud occupies that space and emits a mild chill in the air around it, but it is otherwise indistinct except for a small flurry of snow.    When you cast this spell, you can designate any number of creatures you can see to be capable of interacting with the cloud. While within 5 feet of the cloud, a designated creature can use a bonus action to reach into the cloud, pull out a javelin of magical ice, and throw it at a target within 60 feet. The creature throwing the javelin is proficient with the javelin and makes an attack roll using its Strength or Dexterity modifier (the creature’s choice). On a hit, the javelin deals 2d6 cold damage, and the target’s speed is reduced by 10 feet until the end of its next turn.    The cloud lasts for the duration or until six icy javelins have been pulled from it.
