Demon Slayer ability codex
Demon Slayer ability codex is a members item, with a high alchemy value of 121,200 coins. No shop sells Demon Slayer ability codex and no monster drops it, so an Ironman makes it: it takes 88 Invention and 80 Crafting and gives 10,000 Invention XP and 5,000 Crafting XP, using 100 × Black stone heart, 2 × Onyx and 60 × Silent components.
“Unlocks the Demon Slayer ability.”

Ironman verdict
Where the materials come from: Black stone heart (dropped by Taraket the Necromancer (level 1000)); Onyx (made with 72 Crafting). Making ten takes 1,000 × Black stone heart, 20 × Onyx and 600 × Silent components and gives 100,000 Invention XP and 50,000 Crafting XP. Reaching level 88 Invention takes 4,385,776 XP in total; the Invention calculator counts the actions and materials to any target, and the Invention guide has the Ironman training route. Demon Slayer 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 121,200 coins.
