A dark shadow was seen above the Cobalt Coastlands, then disappeared. You are asked to investigate.

The Request

You will get this request in Jubilife Village after you complete the final mission.

Find Giratina

Giratina can be found in Turnback Cave in Cobalt Coastlands, in the Spring Path area. Approach Giratina to do battle and try to catch it. If you catch it, you get a Griseous Core.

Report to the Professor

The next time you talk to Professor Laventon, the request will be completed, and you will get a Grit Rock.
