After completing Stelumbra Cave - Other Entrance and Hushet Ruins - Other Entrance, go back to Mosso Village and talk to Tereno. He'll say he can make something to get rid of the toxic gas, but it won't be ready until morning, so your party goes straight to the inn, and there's another Free Time event.
To raise everyone's skill level:
- Toril - "Let's give it a light toss!"
- Kodan - "I would give one to the cat."
- Lita - "Start from this difficult chapter."
- Alex (after turning in for the night) - "...I'll take the cookie in the can!"
The next morning, Tenero gives you Poison Thinner, and now you can go back to Breezan Valley. (But first, go back to Hushet Ruins; you can now access Toril's "Skill Level" area near the entrance.)
- Talk to the Old Man next to the weapon shop. He'll tell you about elemental effects and give you 2 tickets.
- 07: Out of this World Chef - Talk to Shermand next to the Storehouse.
- Goblin Ring - located in the northwest corner.
- Tree Saurus Ring
- Bonanza Shirt
- Ability Seed x2
- Weapon+ Ring
