Energy potion (3)

Ironman verdict

You can also make it yourself: it takes 26 Herblore and gives 67.5 Herblore XP, using Harralander potion (unfinished) and Chocolate dust. There is one other recipe below. Where the materials come from: Harralander potion (unfinished) (made with 20 Herblore); Chocolate dust (sold by Funch's Fine Groceries for 20 coins). Making ten takes 10 × Harralander potion (unfinished) and 10 × Chocolate dust and gives 675 Herblore XP. Reaching level 26 Herblore takes 8,740 XP in total; the Herblore calculator counts the actions and materials to any target, and the Herblore guide has the Ironman training route. One recipe uses Energy potion (3): Powerburst of acceleration (4). Energy potion (3) 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 66 coins, which is 44 less than the shop price, so buying it to alch does not pay.
