Alchemy is a process that enables players to get various ingredients from all sorts of activities. Farming, killing mobs, harvesting flowers and much more. You can view the resources you've gained understanding of in [/dex] under the AlchDex section.
To start with alchemy, it's important to understand the basic steps. A large majority of this process will involve fermenting and distilling with ingredients you've discovered.
Heated Cauldron
Brewing Stand (Distiller)
Big Barrels (Aging)
Mortar & Pestle (Crushing)
Combining the outputs of these crafting stations will allow you to create the various potion effects!
In order to create a potion, you need to follow a set of steps, i.e. the amount of ingredients, which ingredients, how long to age etc. You can find lost recipes from:
Once you have a recipe, right click it to add it to your [/dex]. You can view it, again in your [/dex] and you'll be able to make it using the crafting stations above!
The fermenting process is very simple. You take a heated cauldron (any cauldron filled with water above a heat source) and right click it with the proper ingredients. You then wait as long as you need to (TIP: You can right click the cauldron with a clock to see how long it's been!) and right click the cauldron with a bottle. You will get a bottle of ferment you will then either distill or age depending on the recipe.
Distilling is a process where you filter out some unwanted materials. If your recipe calls for it, all you need is a brewing stand & glowstone dust. Put your brew & glowstone dust in the GUI as seen in the image to the right. The recipe may call for it to be distilled multiple times.
Once you've finished distilling, it's on to the final process aging! Note that some recipes may not require distilling or it may be finished after distilling.
Before you can start aging, you first need a barrel to age in! There are two different types of barrels, both require you to build a multi-block structure. The large barrel is 3 blocks wide & 4 blocks tall made out of stairs & planks (see image) and can hold up to 3 row of potions to age. The small barrel is 2 blocks wide and tall made entirely out of stairs (see image again). In order to turn these structures into barrels, you need to place a sign that says Barrel on it. Once you make it a barrel, you can remove the sign and as long as you don't break any of the structure's blocks, the barrel will still work!
Breaking the barrel's blocks does not let you know the structure is broken!
Barrels can be made out of any wood type, so long as it's the same type of wood through-out. For example in the images they're made of oak. I can't mix it with spruce, but I can change all the blocks into spruce versions. This will be important as some recipes require a specific type of wood for aging.
Once you finish aging a potion, you'll be ready to drink it! There are all sorts of potions to find, some of them can only be strictly found due to certain methods (i.e. you won't be able to find the same recipe you got from a message in a bottle in a sunken shop).
