1. Some monumental monuments require players to reach a certain level before they can take them. When the grade is not enough, you can't take these slates.

2. Some stone tablets of immortals are protected. Players need to complete some tasks or defeat some enemies to remove the protection. If you don't finish these tasks or defeat these enemies, you can't take these pills. In Original Sin 2, the tablet of the immortal is a very important object, which can be used to unlock many hidden places and tasks.
