For maximum damage output, people prefer Karil's crossbow, due to the bolts having +55 Ranged Strength, with the same speed as rune arrows with a magic shortbow. Rune arrows are a more cost-efficient alternative to the Karil's crossbow. Despite the presumed expense, as with all ranged ammunition, rune arrows only have a 20% chance to break when fired. Assuming the player wears a device such as Ava's accumulator, 80% of the arrows are returned, giving rune arrows an actual cost of only 17 coins per shot fired.
