Alchemy allows you to combine 2 ingredients to make items. Combining two ingredients results in a 3rd item. Most combinations yield Potatoes, but some yield amazing rewards. Combinations that result in Potatoes are considered failure.
Some Ingredients can be bought from shops In Metrolia and other places in the world.
Ingredients that can be bought from shops are marked with green.
The list of where to buy and buy-able ingredients is work in progress and is incomplete.

Hint 1: Spider Horn + Nenula's Powder = Krieger Horn(+4 MD). Both Ingredients are buy-able and you can max out your mind stats on all chars. This could lead to chars with Mindkillers on having 999 Mind stat.
Hint 2: O Donnell Skull + Spider Horn = Necrotear (Anti Death(100%HP) ~ A tear leeches death). Necrotear is an amazingly useful item. It can be bought from the shop in Underking Castle but this is a cheap way to get Necrotears. Also make money by making and selling them, thou not that much.
Hint 3: Amabranda(Nenuma Village) (WMap 66) - Requires Nenula Code to enter, which can be gotten from Legendary City(Nash Slayer level 7).
