why the price of the formula's material it's so expensive
and where i can bought a material formula purchase by low-cost
most of the components are expensive because they are rare you are going to have craft philosopher's caches [formula at bifrost] for components and alchemist cases [same bifrost] for fomulas. Both formulas made from flowers/paper/ bugs/fish and zomg items all of these are free only pancakes and bait cost anything and they are cheap. The cost for crafting is around 10k for the cache and 15k for the case it takes sometime to make it this way but is far cheaper. not to mention you can sell or trade unused components.
