Unicorn horn dust

Ironman verdict

At least 6 monsters drop it. The easiest is Cave bug (level 6, 2/128); the best rate is Edimmu (level 122), at 10/128, about one every 2 kills. You can also make it yourself: it takes 1 Herblore and gives 1 Herblore XP, using Unicorn horn. There is one other recipe below. Other sources include Alchemist's chest and Zanaris Market trinket stall. Making ten takes 10 × Unicorn horn and gives 10 Herblore XP. 4 recipes use Unicorn horn dust, including Antipoison (3), Cat antipoison and Mixture - step 1 (3). Unicorn horn dust 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 12 coins, which is 8 less than the shop price, so buying it to alch does not pay.
