Weezing Weakness
Type-wise, Weezing takes extra damage from Ground and Psychic. The Poison typing picks up 4 resistances to work with. Levitate grants an additional Ground immunity, reshaping the matchup chart. Weezing's physical bulk (base 120 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |
|---|---|
| 2x (Weak) | Ground, Psychic |
| 0.5x (Resist) | Grass, Fighting, Poison, Bug |
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move
