How to Get Regigigas Mission 24 - Pokemon Legends: Arceus

Travel to the Alabaster Icelands and fly north until you reach the Snowpoint Temple.

Go to the temple, then follow the marker to a locked door.

When you approach the door, the plates on your head will open a path for you.

Go downstairs and approach the LV70 Regigigas to start the battle.

Regigigas is weak against Fighting-type moves.

Regigigas will regain its high Attack and Speed on the 6th turn, so you need to catch it quickly!

Make sure you catch it once it's been weakened.

After you have captured Regigigas, you will get the Blank Plate and complete your mission.
