Off-hand mithril crossbow

Ironman verdict

You can also make it yourself: it takes 33 Fletching and gives 21 Fletching XP, using Mithril crossbow (unstrung) and Crossbow string. Where the materials come from: Mithril crossbow (unstrung) (made with 33 Fletching); Crossbow string (made with 10 Crafting). Making ten takes 10 × Mithril crossbow (unstrung) and 10 × Crossbow string and gives 210 Fletching XP. Reaching level 33 Fletching takes 18,247 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 30 as ranged gear; compare it with every other piece on the Off-hand weapons list. Off-hand mithril 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 270 coins, which is 81 less than the shop price, so buying it to alch does not pay.
