Ironman verdict

You can also make it yourself: it takes 92 Divination and gives 23.4 Divination XP, using 20000 × Incandescent energy and Eldritch crossbow limb. There is one other recipe below. Where the materials come from: Incandescent energy (made with 95 Divination); Eldritch crossbow limb (made with 92 Divination). Making ten takes 200,000 × Incandescent energy and 10 × Eldritch crossbow limb and gives 234 Divination XP. Reaching level 92 Divination takes 6,517,253 XP in total; the Divination calculator counts the actions and materials to any target, and the Divination guide has the Ironman training route. 3 recipes use Eldritch crossbow mechanism, including Eldritch crossbow, Eldritch crossbow limb and Eldritch crossbow stock. Eldritch crossbow mechanism 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.
