Eterna Gym

Eterna City is one of the oldest cities in the Sinnoh region and being so makes it the perfect place to showcase the region’s rich history. While it’s gym is known for their Grass type Pokémon, the same can’t be said for the rest of the city. Once inside the Eterna Gym, the first thing you’ll notice is that it’s full of trees and you won’t be able to see any people apart from the Gym Guide that gives you a brief overview of the gym and cheers you on. So the first challenge would be to find where the trainers are. There are a total of four trainers you need to face before you can face Gardenia. Here’s where you can find them.

The first trainer is located in the northwest area of the gym. If you look behind the tree, you can easily spot the top of her head.

The next trainer is in the southwest area of the gym, just below where the first trainer is located. If you can spot the two brown rocks next to each other, the second trainer is nearby.

The third trainer is the easiest to spot. Located in the southeastern part of the gym, you’ll find some trees that look different from the other trees in the gym. Right behind those trees is the trainer you’re looking for.

The last trainer is located directly north of the third trainer. In a space between the trees, you’ll find the last trainer near the Gym Leader’s platform. 

Most of these trainers will have pure Grass type Pokémon with them so make sure to have Pokémon that are strong against it. Grass types are weak against Fire, Ice, Flying, Bug, and Poison. You probably won’t come by any Ice types at this point in the game but you can easily get Flying and Bug type Pokémon on the way to Eterna City. Starly and Kricketot are solid additions to your team that can easily help you clear Eterna gym. While the trainers are pretty easy to match up against, the same can’t be said for Gardenia.

Gardenia

Gardenia is Eterna City’s Gym Leader. She carries with her some strong Grass type Pokémon that can inflict a bunch of annoying status ailments and can easily sweep your team if you’re not careful. Here are the Pokémon on Gardenia’s team:

  • Cherubi Lv. 19
  • Turtwig Lv. 19
  • Roserade Lv. 22

Cherubi and Turtwig are fairly easy to deal with as long as you have Pokémon with type advantage. Roserade is the real problem and can be difficult to deal with. Gardenia’s Roserade will often lead with Stun Spore to paralyze your Pokémon. If paralyzed, your Pokémon’s speed will be greatly reduced and may not even be able to attack in its turn. 

Out of all the starters, Chimchar is the only Pokémon with a clear advantage against Gardenia. Being a Fire type, it has access to moves that directly counters Gardenia’s Pokémon. Piplup can also be a decent matchup since it learns Peck at Lv. 15 which is a Flying type move. If you chose Turtwig, then you’re better off with getting a Flying or Bug type Pokémon to deal with Gardenia. Since Turtwig is a pure Grass type, it can be susceptible to Roserade’s Poison Sting.

Forest Badge

Once you beat Gardenia, you will get the Forest Badge. This will allow you to use the Hidden Move Cut outside of battle to have Pokémon chop down small trees that often block passageways. You’ll also get TM86 which contains Gardenia’s signature move, Grass Knot. Grass Knot is a Grass type move that deals damage based on how heavy the target is. Pokémon received in trades up to Lv. 30 will also obey you without hesitation. 

Useful Tips

  1. Most of the Pokémon in this gym are around Lv.15 – Lv. 22. Try to get your Pokémon around or above the same levels so that you’ll have an easier time.
  2. Gardenia likes to use status ailments. She’ll favor Paralysis in particular so make sure you stock up on some Paralyze Heals and some Cheri Berries to help you avoid paralysis for an extended duration. A couple of Antidotes and Pecha Berries wouldn’t hurt as well as some of the trainers can inflict Poison on your Pokémon.
