Guthix rest detail

Guthix rest is a restorative potion created during One Small Favour. Once Sanfew teaches the player how to mix the potion, it can be created by using a clean harralander with a vial of water to create a harralander potion (unf), followed by a clean marrentill to create a three-dose Guthix rest, granting a total of 59.5 Herblore experience. Adding a clean harralander to a marrentill potion (unf) will not work. The combined cost of all the required herbs and vial of water would be 358 on the Grand Exchange. However, since they are rarely sold on the Grand Exchange, it may be better to create the potion from scratch.

It reduces damage taken by poison by 10 life points per dose, heals 500 life points per dose, restores 5% run energy and boosts the maximum life points by 500 at full health. A full four dose potion restores a total of 2000 life points.

Attempting to make this potion before speaking with Sanfew will result in: "You have no idea what effect this would have."

The Guthix rest glitch was discovered in the One Small Favour quest.

This item instantly restored 100% of your Hitpoints when a player drank it. It was only supposed to boost the maximum life points if a player was at full health. This glitch was abused to win duels at the Duel Arena and to player kill without dying. This was fixed by Jagex shortly after discovery. Many players were banned for abusing the glitch to gain an unfair advantage in PvP situations.

The glitched potion had the following effects:

  • Cure from poison
  • Restore some run energy
  • Fully heal and boost hitpoints by 5.

  • The Guthix rest used to be drunk from a teacup. This was changed in an update on 20 May 2013.
