Improved Junk Ammo Feat 8

Ammunition you create from scrap and trash is imbued with more special properties. When you create junk ammo as part of your daily preparations, choose two precious materials from the following list: abysium, adamantine, aucturnite, cold iron, siccatite, or silver. The ammunition created with this feat counts as both materials for the purposes of applying immunities, weaknesses, and resistances.
