Adamantine ammunition

This ammunition was made of adamantine. When you hit with this ammunition loaded into the gun, you roll one additional damage die when determining damage but your range is halfed because of the weight of the ammunition.

Firearm bullets are used with a weapon that has the reload property to make a ranged attack. Each time you attack with the weapon, you expend one piece of ammunition but after the fight you can collect the adamantine bullets. On short rests you can put 5 of the adamantine bullet tips back into bullet casingsfor reuse and on long rests you can put 10 adamantine bullet tips back into the bullet casings and when crafting more bullets you'll need a adamantine ingot to make 10 bullet tips
