It possesses the damage traits of Stun Ammo, Incendiary Ammo, Explosive Ammo, and Armor Piercing Ammo, and possess the quantity traits of standard Ammo. Also, like the standard Ammo, it costs two skill points to upgrade to +4. Also note once a player has cryptid slayer ammo, they have the chance to find it in search boxes.
