Off-hand adamant crossbow

Ironman verdict

You can also make it yourself: it takes 43 Fletching and gives 29 Fletching XP, using Adamant crossbow (unstrung) and Crossbow string. Where the materials come from: Adamant crossbow (unstrung) (made with 43 Fletching); Crossbow string (made with 10 Crafting). Making ten takes 10 × Adamant crossbow (unstrung) and 10 × Crossbow string and gives 290 Fletching XP. Reaching level 43 Fletching takes 50,339 XP in total; the Fletching calculator counts the actions and materials to any target, and the Fletching guide has the Ironman training route. It is worn in the off-hand weapon slot at tier 40 as ranged gear; compare it with every other piece on the Off-hand weapons list. Off-hand adamant crossbow 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 340 coins, which is 227 less than the shop price, so buying it to alch does not pay.
