Common Weapon (arrow),

Frost arrows appear as if they are made only of ice. If an arrow hits its intended target, it will often cause 1d8 additional cold damage. This is similar to an arch creating some magical ice.

After it is broken, an arrow filled with frost can do additional damage. Other types of magic ammunition are also available, such as bolts of frost that are intended for crossbows. However, they are much less common than the Arrows.
