Crystal bow

Ironman verdict

2 monsters drop it. The easiest is Edimmu (level 122, 6/16,512); the best rate is Edimmu (elite) (level 125), at 6/5,160, about one every 860 kills. You can also make it yourself: it takes 75 Smithing and gives 750 Smithing XP, using Crystal weapon seed and 750 × Harmonic dust. There is one other recipe below. Other sources include Treasure chest (player-owned port), Motherlode Maw and Wythien. Making ten takes 10 × Crystal weapon seed and 7,500 × Harmonic dust and gives 7,500 Smithing XP. Reaching level 75 Smithing takes 1,210,421 XP in total; the Smithing calculator counts the actions and materials to any target, and the Smithing guide has the Ironman training route. One recipe uses Crystal bow: Augmented crystal bow. It is worn in the two-handed weapon slot at tier 70 as ranged gear; compare it with every other piece on the Two-handed weapons list. Crystal bow is members-only. 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.
