Vulnerability bomb

Vulnerability bomb is a members item, with a high alchemy value of 600 coins. No shop sells Vulnerability bomb and no monster drops it, so an Ironman makes it: it takes 103 Herblore and gives 1,100 Herblore XP, using Bomb vial, Primal extract, 5 × Soul rune, 5 × Chaos rune, 2 × Bottled dinosaur roar and Clean dwarf weed. There are 2 other recipes below.

“Do not drink, aim away from face, keep away from eyes and small children. If substance gets in eyes, face, hands or mouth, wash away with cold water.”

Ironman verdict

Where the materials come from: Bomb vial (sold by Jatix's Herblore Shop for 5 coins); Primal extract (made with 90 Herblore); Soul rune (sold by Baba Yaga's Magic Shop for 410 coins). Making ten takes 10 × Bomb vial, 10 × Primal extract, 50 × Soul rune, 50 × Chaos rune, 20 × Bottled dinosaur roar and 10 × Clean dwarf weed and gives 11,000 Herblore XP. Reaching level 103 Herblore takes 19,368,992 XP in total; the Herblore calculator counts the actions and materials to any target, and the Herblore guide has the Ironman training route. Vulnerability bomb 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 600 coins.
