Snowballs were used to defeat Snowverload during the 2014 Christmas event. They were gathered in stacks of 100 by right clicking him, and there was no limit to how many a player could have at once.
Snowballs returned during the 2015 Christmas event. They were used to pelt the snowmen the player built and also to pelt Snowverload and a few penguins, including General Pinchkin.
They were the only weapons that could harm Snowverload. However, players could not deal the finishing blow to him, which was only done if brought to Santa Claus at the Lumbridge crater.
When players wield snowballs in the Christmas Village, a "pelt" option appears on other players. Selecting this causes the player to throw a snowball at them, losing a snowball.
Although they have tier 30 accuracy and 0 damage stat, they disassemble identically as bronze darts. While they have the attack speed of darts, they have an attack range of 7, same as Morrigan's javelin; they have the longest range of any F2P thrown weapon.
This item's destroy message has changed multiple times. During the 2014 Christmas event it was "You can obtain more snowballs by taking them from Snowverload." During the 2015 Christmas event it was "You can obtain more snowballs by taking them from Snowverload or helping yourself to the enchanted snow behind the Queen of Snow."
