Stats & Training
Mareanie's stats barely vary. None sit in respectable range with no real gaps. It's a blank slate for EV investment. Worth 1 Defense EV, medium-fast 1M XP curve to max.
It plunges the poison spike on its head into its prey. When the prey has weakened, Mareanie deals the finishing blow with its 10 tentacles.
It’s found crawling on beaches and seafloors. The coral that grows on Corsola’s head is as good as a five-star banquet to this Pokémon.
Mareanie Weakness
Mareanie's Poison/Water typing leaves it vulnerable to Electric, Ground, and Psychic. 8 resistances give it solid defensive coverage on top of that.
