Cascoon Weakness
Cascoon is weak to Fire, Flying, and Rock. Cascoon's physical bulk (base 55 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |
|---|---|
| 2x (Weak) | Fire, Flying, Rock |
| 0.5x (Resist) | Grass, Fighting, Ground |
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move
