Ironman verdict

You can also make it yourself: it takes 72 Crafting and gives 180 Crafting XP, using Uncut onyx. Where the materials come from: Uncut onyx (sold by TzHaar-Hur-Lek's Ore and Gem Store for 2,700,000 tokkul). Making ten takes 10 × Uncut onyx and gives 1,800 Crafting XP. Reaching level 72 Crafting takes 899,257 XP in total; the Crafting calculator counts the actions and materials to any target, and the Crafting guide has the Ironman training route. 17 recipes use Onyx, including Alchemical onyx, Artificer's measure and Dark Facet of Grace. Onyx 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. High Alchemy turns one into 180,000 coins.
