While most trainers evolve Qwilfish into Overqwil immediately, the unevolved form has a niche with Eviolite boosting its defenses. Only weak to Electric, Ground, and Psychic. Introduced in Gen 2. Sits at a decent but contested Speed tier.
Attack and Defense carry most of Qwilfish's stat budget. Sp. Atk's the obvious dump stat. Tough to catch and yields 1 Attack EV. Follows a medium-fast 1M XP curve.
Be cautious if this Pokémon starts sucking in water—it will soon attack by scattering the toxic spikes that grow all over its body.
Experienced fishers say they try to catch Qwilfish in the brief moment that these Pokémon become defenseless just after launching poisonous spikes.
Qwilfish Weakness
GoodQwilfish's Water/Poison typing leaves it vulnerable to Electric, Ground, and Psychic moves. With 8 resistances, the defensive profile is strong. Qwilfish's physical bulk (base 85 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
Qwilfish doesn't evolve by leveling. You'll need an evolution item to push it forward to Overqwil. The evolved forms gain up to 70 total stats over Qwilfish.
How to Evolve
Flip Turn keeps your team's momentum going. Qwilfish doesn't need to stay in long, Rocky Helmet provides chip damage on every physical hit received and max Attack and Speed EVs make every visit count. Spikes threatens on the way out. Intimidate adds passive value.
