The game potion formula can be dropped from the fire chemists in the elite strange fire seal Carl and Blackstone Tower copies.

In the game "World of Warcraft", Huoyin Carl is located at the level 56-57 of the copy of Blackstone Tower, and Huoyin Animator is located at the level 57-58 of the copy of Blackstone Tower. The probability of these two elite monsters falling is about 4.3%.

You can choose to team up to brush monsters in the game, which can improve the chances of getting the formula. If you don't want to form a team, you can try to brush these two elite monsters many times. Two elite monsters will randomly drop, and there is a certain chance to drop the formula that the player needs.
