Snow Rocks

Snow Rocks are a throwable item like snowballs except they deal the same amount of damage as the players default punch. Snow Rocks can be used in the early game as a way to deal with mobs from afar. Snow Rocks can also do slightly more damage to Blazes than snowballs. They can naturally generate in igloos and villages in snowy biomes.

To craft Snow Rocks, you'll need one cobblestone in the center and 8 snowballs surrounding it. It will produce 4 or 8 Snow Rocks when crafted. It can be stacked up to 16 and have a cooldown similar to a chorus fruit. They can have the same range as snowballs if not shorter.

Maybe you can give Snow Golems Snow Rocks to use but switch back to snowballs when there are no more Snow Rocks. Kind of like a limited upgrade.
