Thornvine
Thornvine is the rainy Forest Valley attrition wall. Berry starts the route, Leech Seed keeps it alive, and Power Whip gives the page enough threat to matter. Use it when Leaf and Thorn are tied to a defensive plan rather than a fast clear.

Best Use
- Use Thornvine when a team needs rain-resistant Grass defense and Thorn materials.
- Choose it over Bulbin when starter protection is no longer enough.
- Choose it over Tropius when the route is ground forest attrition, not air support.
- A successful run should show that Leech Seed reduces the pressure of the branch.
Team Tips
- Pair Thornvine with a teammate that can handle enemies resistant to Grass damage.
- Let Thornvine absorb long fights while the rest of the party handles burst windows.
- Do not add another slow wall unless the route is built for attrition.
Farming Notes
- Track Thorn as the main reason to return; Leaf is usually the secondary gain.
- Berry is worth spending only when Leech Seed can be used early.
- Stop when the defensive material requirement is finished.
- Return for rainy forest routes where sustain is more valuable than speed.
Common Mistakes
- Using Thornvine for fast Grass farming when a lighter pick would do.
- Waiting too long to apply Leech Seed.
- Confusing its ground attrition role with Tropius-style air support.
