U haveo collect crystals, u will see them they shine in a dark forest. Dont tame raptors just stay close or in a sea and do a tour of the island u will see some crystalls shining close the shore (not all of them). Raptors can not touch u when u are in the sea. If u find some nest with eggs destroy them. To escape raptors u instead the sea u can also climb on rocks or sometimes u can jump on trees and walk above them.
Good luck.
Thanks. I know about the hide-in-the-sea part, I was just wondering about the crystals (as they're so damn heavy to carry around with all my other stuff) and whether the "friend" existed and where he/she is on the island. So if I finish collecting all the crystals, will the "friend" show up?
