A tiny snowball is fired and grows in size every time it hits the ground. The larger it is when it hits an enemy, the more damage is dealt. If it becomes too large, it will explode upon hitting the ground.
Landing the snowstorm on flat land right on a player can cause up to 165 damage with no Crits because of the area of effect of the snowballs.
If shot on flat land at 3 Power and 0 Angle, the Snowball will explode just outside the side of your tank dealing no damage to you. The enemy tank must be at least two-thirds a tank length away for maximum damage. (Measured from edge of tank to edge of tank.)
If shot on flat land at 33 Power and 0 Angle, the Snowball will hit a tank at the edge of Power circle with the maximum possible damage of 105 without Crits.
