How to Beat Allister

Raise a Ghost or Dark-type Pokemon to Level 35

Allister, the Gym Leader of Stow-on-Side, uses Ghost-type Pokemon, so it's advisable to take him on with a strong Ghost or Dark-type Pokemon in your party.

Allister's strongest Pokemon is a Gengar at Level 36, so having a Ghost or Dark-type Pokemon at Level 35 or higher will make the battle easier to handle.

Catch a Yamask or a Dugtrio on Route 6

Galarian Yamask

Dugtrio

If you haven't caught any Pokemon with Ghost or Dark-type Moves up to this point, catching a Yamask or a Dugtrio on Route 6 can add balance to your team. Yamask will learn the Ghost-type Move Hex, while Dugtrio will learn the Dark-type Move Sucker Punch, which can be useful for players of Pokemon Shield in taking on Allister's Ghost-type Pokemon.

Have a Pokemon who can handle Gengar's attacks

If your Pokemon's levels are low coming in to the fight, put in a Pokemon who can withstand Gengar's Dynamax attacks. If one of your Pokemon can withstand 3 attacks from Gengar's Dynamax form, it will return to its normal form and become easier to handle for the rest of the battle.

Stock up on Revives, Super Potions, and X Special Defend

Allister's Pokemon deal heavy damage, so have these items along as insurance to help make it through the fight. X Special Defend can also be handy for your lead Pokemon to help them weather special attacks.
