Bullets are ammunition for guns and the Gun Staff. To fire a gun you must first have the correct bullets in your inventory. Push Sneak+Right Click to load the bullets into your gun. The Sneak function is usually assigned to the Shift-Key
Iron Bullets[]
These are the standard bullets for this mod. They do the default damage of the gun, and can be found in dungeon chests.
Gold Bullets[]
Gold bullets appear to do more damage. When using a musket from the creative menu, it looked to be adding 3-5 damage.
Fire Bullets[]
Oddly enough, when testing these bullets, they did base damage and did not set anyone or anything on fire.
Magic Bullets[]
Like the fire bullets, these bullets do not cause any magic effects, but only do base damage.
Cannon Bullet[]
The Cannon Bullet is only compatible with the Cannon. It can also be seen when using the gun spear. If you fully charge it up, then release, it will fire a cannon bullet. So far I have only found one it dungeon chests.
