Weathered Relic

The Weathered Relic is found in the Feldust Cavern (mouth at ) on the Broken Shore at the very back of the cave after talking to Drak'thul. It is used to attune players to Kosumoth the Hungering.

Players will not be able to access the cave until after speaking with Drak'thul the first time and exhausting is gossip text.

Return to Drak'thul after picking up the relic to continue the chain.

Speculation
This relic may be the same relic that reanimated the orcish skeletons during the Warcraft III mission The Broken Isles, and they share the same icon.
