As a Pokemon enthusiast, the transition of Feebas, the disheveled-looking fish, into Milotic, the elegant sea serpent, is a fascinating journey set in the world of Pokemon Scarlet & Pokemon Violet. However, accomplishing this is a challenging task. Buckle up as we delve into this step-by-step guide that helps decode the intricacies involved in evolving Feebas into Milotic.

Step 1: Acquiring Feebas

Acquiring Feebas

Your journey to get a splendid Milotic begins with capturing a Feebas first. In Pokemon Scarlet & Violet, Feebas is elusive and rare, populating a specific region in Kitakami. To catch Feebas, you'll first need Koraidon/Miraidon’s ability to swim if you plan to Shiny Hunt, team up with a Pokemon adept in water combat with a superior type effectiveness over Water-type (for instance, Wattrel - an Electric/Flying-type).

Step 2: Traversing to Oni Mountain

Navigate to the Crystal Pool, cross the bridge leading to a hill with an inclination, and enter the cavern at the edge of this hill to arrive at Oni Mountain. There forget the Kitakami Ogre Clan trainer and proceed further down, towards a water body. Swim downstream and vanquish the obstructing Whiscash. Following these actions will raise your chances for the elusive Feebas to garner.

Step 3: Battling Maneuvers

First, bear in mind that Feebas possesses the tendency to flee and dive underwater when players get too close, hence launching a Pokemon to combat with the ZR-button, avoiding the R-button. To increase the frequency of Feebas encounters, consider preparing a sandwich that carries an Encounter Power: Watermeal effect.

Step 4: Advanced Catching Techniques

Advanced Catching Techniques

Upon spotting a Feebas, implement a Quick Ball on the initial turn. If unsuccessful, opt for Net Balls or Dive Balls. An important catch secret lies in having a certain patience - bear in mind Feebas are rare, and you might cross paths with several Barboach before you encounter a Feebas. Wipe out the Barboach with Auto-Battle mode to enable more Feebas encounters. Those struggling with Feebas discovery can inspect 3-star Tera Raids in Kitakami.

Step 5: Transitions into Milotic

Your prized possession, a Feebas, will evolve into Milotic once you make it, hold a Prism Scale and proceed to trade it. A Prism Scale, one of the rewards for capturing 140 Pokemon in Kitakami, kindles the evolution. For trading, you'd require an Online Membership, post which you can kick-start a Link Trade via the Poke Portal.

Step 6: The Alternative Route

If you want to explore an alternative method to evolve Feebas, you can do so by using Pokemon HOME and Pokemon Brilliant Diamond or Shining Pearl. After you've caught a Feebas in Scarlet/Violet and transferred it to BD/SP via HOME, head to Hearthome City's Poffin House. Here, feed Feebas with "high-leveled" puffins created by blending four different types of "dry" berries. Continue feeding until it maxes out its "Beauty" stat, post which, level it up once, and voila! Your Feebas is now a splendid Milotic.

This captivating transformation journey from Feebas to Milotic showcases the broad canvas of possibilities that Pokemon Scarlet & Pokemon Violet offer, making it a game saturated with excitement and intrigue at every corner.
