Other sources include Ava's accumulator and Ava's alerter. Making ten takes 100 × Steel bolts (unf) and 100 × Feather and gives 350 Fletching XP. Reaching level 23 Fletching takes 6,291 XP in total; the Fletching calculator counts the actions and materials to any target, and the Fletching guide has the Ironman training route. One recipe uses Steel bolts: Topaz bolts. It is worn in the ammunition slot at tier 20 as ranged gear; compare it with every other piece on the Ammunition list. Steel bolts is available on free-to-play worlds too. It is tradeable on normal accounts, but an Ironman cannot use the Grand Exchange or trade for it, so the sources on this page are the whole list. High Alchemy turns one into 4 coins, which is 4 less than the shop price, so buying it to alch does not pay.
