Off-hand bronze crossbow

Ironman verdict

Only one monster drops it: Zombie (New Varrock), at 1/512 (about one every 512 kills). You can also make it yourself: it takes 3 Fletching and gives 4 Fletching XP, using Bronze crossbow (unstrung) and Crossbow string. Other sources include Zombie (New Varrock). Making ten takes 10 × Bronze crossbow (unstrung) and 10 × Crossbow string and gives 40 Fletching XP. Reaching level 3 Fletching takes 174 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 5 as ranged gear; compare it with every other piece on the Off-hand weapons list. Off-hand bronze 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 122 coins, 18 more than the shop price, before the cost of the nature rune.
