The Blackrock Feather is one of the many feathers that can be obtained in the Frontier. They are naturally obtained from the Blackrock Bird species. The Blackrock Bird is most commonly found everywhere in Blackrock Mountain, but may also make occasional appearances in the graveyard of Topple Town or on the plant life of A Frontier of Dragons. They can be differentiated from the Blackbirds based on the fact that it's rather fat and plump.
Not much can be said about its appearance, other than the fact that the feather is pitch-black to the point where you can see the dividing layers of the vanes.
It is possible for players to exchange Blackrock Feathers for gold during Slayer's Tasks if the task card is currently active. Besides that, the Blackrock Feather can be sold to a selling vendor at a selling price of 2,000 gold.
- The Blackrock Feather is not to be confused with the Black Feather.
