Stats & Training
Tentacool's spread isn't flashy. Sp. Def leads, Defense trails, 1 stats clear the bar. Common in the wild and worth 1 Sp. Def EV, on a slow 1.25M XP grind.
They fire beams from the glassy, magenta orbs that resemble eyes atop their heads, and they drift in shallow seas. During low tide, they can sometimes be found on beaches, desiccated.
Tentacool Weakness
Tentacool is weak to Electric, Ground, and Psychic. 8 resistances give it solid defensive coverage on top of that. Tentacool's special bulk (base 100 Sp.Def) helps absorb special-type weaknesses, though physical moves exploit the lower Defense.
| Damage | Types |
|---|---|
| 2x (Weak) | Electric, Ground, Psychic |
