Reaching level 95 Divination takes 8,771,558 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 Obsidian blade, including Ancient hilt, Ek-ZekKil and Magma core. Obsidian blade 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.
