You cause a Tiny white flower to sprout at a point on the ground you can see within range. The flower has an AC of 15, 1 hit point, vulnerability to fire damage, and immunity to cold damage. During the spell’s duration, you can use a bonus action to command it to explode in a shower of ice. Alternatively, the flower will explode if it is reduced to 0 hit points. When the flower explodes, each creature within 30 feet of it must make a Dexterity saving throw. On a failed save, a creature takes 6d8 cold damage and loose 10ft of movement, or half as much damage and avoid the speed reduction on a successful one.
