Stats & Training
Shellder's spread isn't flashy. Defense leads, HP trails, 1 stats clear the bar. Common in the wild and worth 1 Defense stat exp, on a slow 1.25M XP grind.
The shell can withstand any attack. However, when it is open, the tender body is exposed.
Shellder Weakness
Type-wise, Shellder takes extra damage from Electric and Grass. Its Water typing keeps the defensive matchups simple. Shellder's physical bulk (base 100 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |
|---|---|
| 2x (Weak) | Electric, Grass |
| 0.5x (Resist) | Fire, Water, Ice |
- Only 15 types exist — Dark, Steel, and Fairy are absent
- Ghost has no effect on Psychic (a known bug, fixed in Gen II)
- Special stat governs both offense and defense — no Sp.Atk / Sp.Def split
