Ritual Conch
From WikiRaider
The Ritual Conch is a Relic found in Lara Croft: Relic Run. It is the 17th relic that can be found in the Jungle Temple after collecting 24 clues in the 34 level. (Originally 58 clues in endless mode before version 1.5.68.)
This piece is a ritual conch. The priests would sound it at dawn to pull the sun out of the shadows. There's a pattern to all this somewhere.
