You summon a tiny elemental creature in the form of a particularly aggressive, and self destructive, Savage Snowball (see my homebrew monster of the same name). When the creature appears, you point at a creature you can see. The snowball recklessly approaches and attacks that creature, if able. Otherwise, it doesn't move and takes the dodge action until you use a bonus action to give it a new target.

The summoned creature is friendly to you and your companions. The summoned creature acts immediately after you cast this spell and share your initiative. The DM has the creature's statistics.

At Higher Levels. The number of snowballs that you can summon increases when you reach 5th level (2), 11th level (3), and 17th level (4). If you summon more than one creature with this spell, all creatures summoned will have the same target. This applies each time you issue a new target as well.
