Relic Finder is a medal/trophy in Uncharted: Golden Abyss.
How To Find It
The Strange Relic can only be found in Chapter 15: "Chimera to Ward Off Evil". Before or After you open the door for Chase, go behind you and climb up the walls that show hand holds. When you reach the very top of the hand holds, an icon of a hand appears, click on the icon and it will tell you to wipe the Strange Relic clean. When you're done cleaning the Strange Relic, you have then earned it and a medal/trophy will appear which means that you have collected the medal/trophy.
