The Fantasia potion in Final Fantasy XIV allows you to customize the appearance of your character in the game. You can go far to change the physical aspects of your character and race. The things that will remain the same will be your character’s server, starting city and name. The potion does not change any of these factors. A potion is a disposable item.
Because the item is disposable when you drink it, it is a rare item. Normally, you can only get it by purchasing it from Mogstation for Final Fantasy XIV. However, you can also get one Fantasia potion by completing The Ultimate Weapon quest. You can start by talking to Raubahn in Northern Thanalan vx: 15, y: 16. You get this quest by going through the Seventh Umbral Era series, which begins with the Rock the Castrum quest you receive from Raubahn.
After drinking the Fantasia potion, you only have one chance to adjust your character in any way. You want to make sure that before you do that, you remove all weapons and armor from your character. When they change to their new look, there are usually some problems with the potion, so it’s better to have nothing equipped.
Then you can give them a brand new race and start from scratch to make sure you don’t have to create a brand new character on the server you’re playing, especially if you want to create one of the races offered in Final Fantasy XIV in the future, especially Male Viera or female Hrothgar. You can make all the changes to the appearance of your character by logging out and making them from the login screen, where you start the game Final Fantasy XIV.
