If you’re looking to evolve Sliggoo into its final form, you’re in the right place. This guide will walk you through everything you need to know—how to get Sliggoo in the first place, when it evolves, special conditions you must meet, and some tips to make the process easier. The steps are explained clearly so even if you’re new to the series you’ll have no trouble.

Before you can evolve Sliggoo, you’ll need its earlier evolution. Here’s how it works:
- First, you’ll find Goomy. Goomy is a Dragon-type introduced in the sixth generation of the games.
- Goomy evolves into Sliggoo at level 40.
- Once you have Sliggoo, you’re ready to aim for its final evolution.
If you already have Sliggoo, skip ahead to the conditions for evolving it.
How Sliggoo Evolves: The Key Conditions
Evolving Sliggoo isn’t just a matter of reaching a certain level—it has a weather condition attached. Here are the details:
- Sliggoo evolves into Goodra starting at level 50 only if it levels up during rain in the overworld.
- Importantly: artificially triggered rain (for example by using the move Rain Dance or weather abilities like Drizzle) does not count. It must be natural rain in the game environment.
- This means you’ll want to find a location in the game where it is raining naturally, then level up Sliggoo to at least level 50 while the rain is active.
Why This Evolution Method Exists
- The developers designed Sliggoo’s evolution with a weather-condition to make it more interesting and to reward players who explore the world and time their progress.
- It adds a small puzzle element: you can’t just grind to level 50; you must also monitor or wait for rain.
- In games where the environment’s weather is dynamic, this adds a fun layer of strategy and patience.
Step-by-Step: How to Evolve Sliggoo
Follow these steps to evolve Sliggoo smoothly:
- Obtain a Goomy and raise it to level 40 so it evolves into Sliggoo.
- Continue to train the Sliggoo until it is at or near level 50.
- Find an area in the game where natural rain is occurring. (Check weather forecasts in-game or visit regions prone to rain.)
- While in rain, gain a level (for example through battle or experience items) so that Sliggoo reaches level 50 or above during the rain.
- If done correctly, Sliggoo will evolve into Goodra when it levels up at that time.
Tips & Tricks to Make It Easier
- Choose game areas where it often rains or where the weather is more likely to change to rain.
- Be ready when rain starts: if you have Sliggoo at level 49, you can use Rare Candy or battle once to hit level 50 while it’s still raining.
- Keep experience-boosting items ready so you don’t waste time once the rain condition is met.
- Monitor the weather clock in the game; sometimes rain may only last a short time, so timing matters.
- If possible, save the game right before rain begins, so if you do the level up and it fails (for example because the rain ended) you can reload and try again.
Special Note: Regional/Form Variants
- In certain games there are regional forms and variations of Sliggoo (for example a form found in the region of Hisui).
- While the core evolution rule remains the same (level 50 + rain), always check if your specific game version or regional form imposes any extra conditions.
Common Mistakes to Avoid
- Waiting until Sliggoo is above level 50 but doing the level up when it’s not raining: the evolution will not trigger.
- Using a move like Rain Dance to cause rain and then leveling up: this will not count. The rain must be natural.
- Assuming that getting to level 50 alone is enough: it’s not. The weather condition is vital.
- Being in an area with rain but leveling up after the rain ends: timing matters—make sure the level up happens during active rain.
