Sliggoo, introduced in Pokémon X and Y, requires more effort to evolve than most Pokémon.This is due to the fact that it must be raining in order for Sliggoo to evolve.When Sliggoo becomes the Dragon Pokémon Goodra, it will become a flightless Pokémon that can throw punches.
Step 1: It should be at least Level 50.
You have to accumulate 10 levels before you can evolve into Goodra.You can raise Sliggoo's level by fighting.Sliggoo is strong against Fire, Water, Grass, and Electric.It is great against a lot of the starter and wild Pokémon, but can lead to tough fights against other Dragon-types.Gain enough experience to almost hit Level 50 and then stop if you can raise Sliggoo to Level 49.When it rains, this will allow you to quickly level it.
Step 2: It's a good place to find a rainy spot.
It can only evolve when it is raining.You can find rain in the following areas: X and Y - Routes 8, 10, 14, 15, 16, 19, 21, Shalour, and Couriway.It can take a long time for rain to show up.You'll find yourself in a rain eventually if you stay patient.Don't forget to take care of other things.When you least expect it, you'll probably happen across some rain.It is always raining on Route 120, which is the perfect place to evolve Sliggoo.Sun, Moon, Ultra Sun and Ultra Moon are games that are played in Po Town, which is always raining.Rain Dance will not cause the evolution.Natural rain is what it must be.
Step 3: To evolve into Goodra, level up Sliggoo in the rain.
You can either fight a battle that will give Sliggoo enough experience to level up or you can give it a rare candy.It must be at least Level 50 before it can evolve.
