Well it depends on what you want to use with it. These tools are used for alchemy (making potions) you might need the mortar and pestal to? These will raise your chances of making a potion, and the potion's strength. First you need ingredients that have the same side effects like restore fatigue,( and if one ingredient happens to have another side effect besides restore fatigue you can add another item that has the other effect, thus adding that efeect to the potion itself.)
Ex 1. Violet Russela (Mushroom); Water breathing, restore health
2. Kowama egg; Restore heaalth
3. Pearl; Water breathing. (If the Third ingredient has another side effect of water breathing it will add it to the potion.)
Therfore the potion you make shoud give you (restore health ##Pts water breathing ##Pts.)
Although this is a complicated one, it works just as well with just 2 ingredients.
Hope this helped
