After exploring Route 7, you enter Wela Volcano Park to find Kiawe and start his trial.
Explore the Volcano
Go to the left through the grass, then go up the ramp up above. Go downward to find a Hyper Potion.
Go to the left through the grass. Then go up and you can battle Sightseer Mariah. She has a level 19 Meowth. You get 1140 Pokédollars for winning.
Continue going up the path and you find a cave. Go in and you can talk to the girl on the right to heal your pokémon.
There is a one-way ledge to the left. If you go that way, you will find a green sparkle to collect in the Zygarde Cube.
Keep going along the one-way path to find Charcoal.
Go into the cave at the bottom to go to the right side of the volcano.
To the south, you can battle Ace Trainer Jim. He has a level 21 Kadabra. You get 1428 Pokédollars for winning.
Farther south, there is a ramp that you can go down to get TM39 Rock Tomb.
There is a Poké Finder spot where you found the TM. You can take pictures there.
If you go downward on this ledge, you can battle Hiker Calhoun. He has a level 18 Roggenrola and a level 19 Machop. You get 608 Pokédollars for winning.
Go to the left from here and go down a series of one-way ledges to find a Burn Heal.
Go down from there and you will be back at the first cave that you went through in the volcano.
Go into that cave and talk to the girl on the right again to heal up. Then go through the Captain's Barrier next to her. You'll enter the Totem's Den.
Wela Volcano Park Totem's Den
Go up to the platform in the middle to find Kiawe. He will ask if you are ready for the trial.
If so, Kiawe will show three Marowaks dancing. You have to figure out which of the three Marowaks did something different between the two dances. One of the Marowaks will do a different pose at the end of the second dance. There is no penalty if you ask to see the dances again. Click the button if you want to know the answer.
After you give the correct answer, you battle the level 18 Marowak. It can't be caught.
After that, you are asked to say the difference between another two dances. Click the button if you want to know the answer.
After this, you battle Hiker David, who has a level 19 Magmar. You get 608 Pokédollars for winning.
Now Kiawe shows you the final dance. Once again, the difference is at the end of the dances. Click the button if you want to know the answer.
After you get the correct answer, you battle the level 22 Totem Salazzle. It is very weak to Ground attacks, and weak to Rock, Water, and Psychic attacks. It can summon Salandits into the battle.
After you defeat the Totem Salazzle, Kiawe gives you Firium Z, and the trial ends. Kiawe gives you 10 Quick Balls, which increase your chance of catching a pokémon if you use them as soon as the battle starts. Kiawe also adds Charizard to your Ride Pager.
When you use the Ride Pager to ride Charizard, it is just like using Fly in previous games. You can instantly go to any Pokémon Center that you have been to before. This makes it easy to go back to Melemele Island any time.
Now that Charizard has been added to your Ride Pager, your X-button menu now has Poké Pelago.
When you are ready to continue, you should go to the tunnel in Route 7 and talk to the person in front of the barricade to open it. Go into the tunnel to reach Route 8.
