Super Restore Recipe

To make super restore potion, you need to reach level 63 in Herblore. Once you’ve done that, combine these ingredients:

  • Snapdragon x 1
  • Vial of water x 1

Now, add one quantity of red spiders’ eggs to the Snapdragon potion you just made.

Before brewing the serum, you will need at least level 65 Herblore and completion of Zogre Flesh Eaters, which is a quest in the Feldip Hills area. You will also need an untradeable item called snake weed. Search the marshy jungle vines in south-west of Tai Bwo Wannai. Players can also get snake weed as a drop from Jogres and Tribesmen.

You can make Sanfew serum by adding unicorn horn dust, clean snake weed, and nail beast nails to the super restore potion you made. Note: All ingredients will have to be in a single quantity. Also, pour them in the order mentioned.
