Gyaling Horn
From WikiRaider
The Gyaling Horn is a Relic found in Lara Croft: Relic Run. It is the 14th relic and can be found level 108, the 28th in the Mountain Pass region, after collecting ?? clues.
Blowing this horn sent some of Rahu's minions scurrying. The relics are definitely his Achilles heel.
