Tomb Raider: Legend

If there are difficulties in calculating the silver relics, then in the mansion it is very easy to miss one of such details as one silver relic. I’ll tell you right away, so as not to get confused, in Lara’s Mansion there is one on the right side of the main hall, going up the stairs. There you will need to shoot the round beam, and there will be the first silver relic. Then there will be 2 more silver relics in the library, and there will be another silver one in the basement. And I counted three such silver relics in the Training Hall, and there is also one of the silver relics between the pool and the Training Hall. In the very place where the pool is, there are two more silver relics, one of which you can definitely miss, one of which is where the statue of a fish with a ball is located, you will drop one to get to the elevator, and behind the other fish hides the very trophy that you have been looking for for a very long time and thought It's some kind of bug.
I hope I could help someone.
So if this video can help you.
