Threefold Bolt

Infuse a ranged weapon with icy magicks, causing it to generate a bolt of magical ice. The bolt splits into three when you fire it, and you can direct the bolts to strike multiple targets or one. For each bolt, make a ranged weapon attack against a creature you can see within range, using the weapon used to cast the spell. On a hit, a target takes 2d4 Cold damage instead of the weapon's normal damage. Then, after making all three attack rolls, each creature successfully hit by one or more bolts must succeed a Strength saving throw or be knocked prone.

At Higher Levels. When you cast this spell using a spell slot of level 2 or higher, the damage this spell deals on a successful hit increases by 1d4 for each slot level above 1. When you cast this spell using a spell slot of level 5 or higher, a hit target makes the Strength saving throw with disadvantage.
