Ironman verdict
Where the materials come from: Codex of lost knowledge (from Zamorak, Lord of Chaos). Making ten takes 10 × Codex of lost knowledge and 200 × Cywir components and gives 100,000 Invention XP. Reaching level 85 Invention takes 3,258,594 XP in total; the Invention calculator counts the actions and materials to any target, and the Invention guide has the Ironman training route. Greater Death's Swiftness ability codex 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 750,000 coins.
