The alchemy pot is required to brew potions. There are sets of potions (alpha, beta), each of them require different ingredients. For each set it is necessary to choose certain quantity of ingredients and put them in an alchemy pot. All pots receive different combinations of ingredients for each potion, you have to guess them. There can be other combinations in other pots of the player.
Each pot has 3 brews a day. If you guess correct combination with the first brew you can make same potion 2 more times till the end of day, using same set of ingredients. If you guess a correct combination with the third brew it will be the last one.
Attention. The more one kind of ingredient is used (by all the players across the world), the less chance it has to be included in the next day's sequences.
