Pokemon Legends: Arceus shows how life was in ancient times, where the Sinnoh region was known as Hisui instead. In this vast place with many biomes to visit and challenges to face, you will see classic pokemon that you can catch as you did in prior games. However, some of these creatures will present several differences that can either change their typing or introduce entirely new evolutionary steps.

This Basculin will be a bit different from the ones we already know, and instead of having red or blue stripes it will sport white ones and will change its colors as it evolves into the newly introduced Basculegion, a giant Water/Ghost-type pokemon that will look very different depending on its gender.

How To Get Basculin

To obtain a Basculegion you must catch a Basculin first, which you can find by surfing in the following zones of various areas in the Hisui region, only accessible by using the Ride Basculegion to move across the water:

  • Cobalt Coastlands
    • Tranquility Cove (Female Only)
    • Islespy Shore (Male Only)
  • Coronet Highlands
    • Fabled Spring
  • Alabaster Icelands
    • Lake Acuity
    • Heart's Crag

How To Get Basculegion

While you can ride a Basculegion to surf in water bodies, you won't be able to use one in battles unless you catch its basic form first. After having obtained your Basculin, all that remains is to evolve it to its next evolutionary step. To successfully do this you must unlock the new attack move Wave Crash, level up until it masters it, and use it in battle until you inflict yourself a total of 294 damage in recoil without fainting. If you proceed correctly after you finish with this process you will unlock the ability to evolve Basculin into its evolution form, Basculegion, a Water/Ghost pokemon that will have a different aspect and color depending on if it's a female or male one, and will gain access to moves like Shadow Ball, or Hex.
