Blizzard

You launch a blue orb filled with ice at a targeted creature. The orb may bounce once or twice, so even if it doesn't land on the target, it will still bounce as long as it's within a 10 foot radius, which means the attack roll is extremely low. Once targeted, 25 bolts of ice fall from the sky dealing 1d8 cold damage per bolt which means 25d8 cold damage in total. The projectiles freeze the ground on contact. Once that happens, the target cannot move for 8 minutes, however they can make a Constitution saving throw. If failed, they will also take 1d6 cold damage each time it's the turn six times.
