Rune arrow heads can be obtained from Smithing a Rune bar on an anvil at level 90 Smithing. One bar produces ten arrow heads, and gives 75 smithing experience. With a Fletching level of 75 they can be attached on Headless Arrows, to gain 125 Fletching experience and Rune Arrows.
Obtaining from Stores[]
They can also be purchased from Hickton's Archery Store in Catherby, which has a stock of 100 arrow heads for 400 GP each, a total of 40,000 GP, making these the most expensive arrow heads in the game.
