Adamantite ore

Ironman verdict

You can also make it yourself: it takes 48 Divination and gives 15.7 Divination XP, using 2 × Sparkling energy and 3 × Mithril ore. Other sources include Thalassus, Bag of lost items, Divine adamantite rock and Balthazar's Bargain Barrel, plus 2 more listed below. Where the materials come from: Sparkling energy (made with 10 Divination); Mithril ore (sold by Ore Store for 59 coins). Making ten takes 20 × Sparkling energy and 30 × Mithril ore and gives 157 Divination XP. Reaching level 48 Divination takes 83,014 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 Adamantite ore, including Adamant bar, Runite ore and Superior locator. Adamantite ore 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 50 coins, which is 34 less than the shop price, so buying it to alch does not pay.
