Trivia

• Defence potions used to be made with clean ranarr and white berries, requiring a Herblore level of 30 and giving 75 Herblore experience.
  • Using white berries on a ranarr potion (unf) now yields the message "A defence potion is now made using a Tarromin potion (unf)." As defence potions are now made with a marrentill potion (unf), it appears that this is a textual error. This has been fixed.
• Previously, during the Jekyll and Hyde random event, if a clean toadflax herb was given to Dr. Jekyll, he would give out a defence potion.
