Things You'll Need
Instructions
Focus on getting Feebas' beauty to its maximum level. The maximum beauty a Pokemon can have is 200, and Feebas must reach 170 before it evolves into Milotic. Before you decide to get its beauty high, ensure that Feebas is leveled high enough through experience, which you get when you use him in battles.
Gather different types of berries to feed to Feebas. The best-rated berries are pamtre berries, which you need to go to Amity Square to find. You have a chance of picking up pamtre berries when your Pokemon grabs items in the square. Pamtre berries increase beauty by 30 points. Go to Route 208 to purchase wiki berries from the berry master or encounter them in the wild on routes 210 and 215.
Use Feebas in a battle to evolve him into Milotic. He will evolve after a few fights or if you use a rare candy on him.
