Snowball

Throw it at your teammates, mostly. The snowball is a holiday item with no recipe and no blueprint, and it turns up around the winter event rather than at a workbench. Hitting someone with it is a laugh, not a kill, and it will not chase a roamer off your door either.

Its one practical use is ammo. The snowball gun loads them, so if someone in your group built one, hand your snowballs over instead of throwing them by hand. Without the gun they are just a toy.

They do not stack, so every ball takes a slot of its own. Keep them out of your hotbar on a raid or a roam. For winter decoration at the base, a snowman does the job better, and the rest of the weapon list holds what you actually fight with.
