Seeking the Remaining Plates Mission - Pokemon Legends: Arc
Once you have collected all the pieces of the last Plates, return to Cogita at the Ancient Retreat. Report your progress in finding them.
Collect 3 logs of wood and bring them to Cogita.
Travel to the Coronet Highlands and meet Volo at the Sacred Plaza.
Go to the Temple of Sinnoh, and defeat Volo.
In the battle against Giratina and Volo, you will face a series of 8 consecutive battles.
Before you start, make sure your team is ready.
Bring Pokemon that focus on fairy, rock, and ground-type moves.
In other words, these are enough to cover the weaknesses of Volo's guide.
In the second phase of the fight, Fairy type Pokemon will also be helpful.
The Volo team includes Spiritomb, Togekiss, Roserade, Hisuian Arcanine, Lucario, and Garchomp.
After you beat Volo, Lv70 Giratina will appear. It will immediately challenge you to a battle.
You can't catch Giratina right now. Your only option is to defeat its Altered Form and Origin Form.
If you lose either battle, you'll start over from Volo.
After you beat Giratina, Volo will give you the Spooky Plate.
