TheHere you are:
player.ammoCost75 = true; // 25% chance to not consume ammo
player.ammoCost80 = true; // 20% chance to not consume ammo
Other things about this:
player.ammoBox = true; // Ammo Box buff (20% chance to not consume ammo)
player.ammoPotion = true; // Ammo Potion buff (I forgot what it's do)
I think I help you!
player.ammoBox = true;
worked, but not the player.ammoCost80 = true;
, thank you regardless I just needed the ammo reduction.
