Crystal Bullet

Crystal Bullet is an ammunition item from 1.1 update. They are crafted with 25 musket balls, and 1 Crystal Shard on the Mythril Anvil. These bullets are split into crystal shards when they are shot into tiles.

The Crystal Bullets, when shot, pierce through enemies akin to the Meteor Shot (though they don't bounce off surfaces), and when they hit a solid block they split into small crystal particles that have a limited range and deal little damage to enemies.This makes this type of ammo useful for fighting enemies on the ground as well as large bosses like the Destroyer, as they can be shot at the enemy's feet to maximize damage.
