Spikes and Venom: Evolving Hisuian Qwilfish into Overqwil in Pokémon GO

The introduction of regional variants from the ancient Hisui region brought new evolutionary life to classic Johto species. While standard water and poison Qwilfish possess no further evolutionary stages, Hisuian Qwilfish evolves into the formidable sea-mine juggernaut Overqwil.

Trainers inspecting their Hisuian Qwilfish will notice a locked evolution icon. In addition to a standard Candy requirement, Niantic requires completing a specific buddy-linked battle milestone before evolution is granted.

Below is the verified procedure to unlock Overqwil efficiently while minimizing unnecessary raid expenditure.

Prerequisites for Overqwil

Evolving Hisuian Qwilfish demands completing two distinct criteria:

Evolution Requirements:

1. Candy Requirement: 50 Qwilfish Candy (standard and Hisuian species share the same Candy pool).
2. The Buddy Challenge: Win 10 Raid Battles while Hisuian Qwilfish is designated as your active companion.

Standard Johto Qwilfish cannot evolve into Overqwil. Verify you are using the Dark and Poison regional form featuring a black and deep purple body.

Step-by-Step Walkthrough: Completing the 10 Raids

Follow these steps to track your battle progression correctly:

Step 1 Set Hisuian Qwilfish as Your Buddy:

Navigate to your inventory, select your desired Hisuian Qwilfish, and tap Set as Buddy. Feeding berries to bring the companion onto the physical map is not required; it merely needs to be assigned to your buddy slot.

Step 2 Win 10 Raid Battles:

Engage in and successfully clear ten Raid Battles.

Important: Your Hisuian Qwilfish does not need to participate in the actual combat arena. It can remain on your party bench or stay out of the raid party entirely, provided it remains your designated active buddy throughout the encounter.

Strategy Tip: Target local 1-Star Raids that can be cleared solo in under thirty seconds using daily free Raid Passes.

Step 3 Execute the Evolution:

Once the progress gauge hits 10/10, the evolution lock opens. Spend 50 Candy to register Overqwil in your Pokédex.

Overqwil's Competitive Value in PvP

Overqwil holds an established position within Great League and restricted themed cups:

1. Elite Defensive Typing: As a Dark and Poison dual-type, Overqwil carries only a single weakness to Ground, while resisting Grass, Poison, Ghost, Dark, and holding an immunity to Psychic.
2. Shield Pressure: Poison Jab combined with rapid Aqua Tail shield-baiting keeps opposing leads off balance.
