Zamorak brew

Zamorak brews are made by mixing torstol and jangerberries in a vial of water, giving 175 Herblore experience. It requires level 78 Herblore.

Zamorak brews temporarily raise Attack by 20% +2, and Strength by 12% + 2. It also temporarily lowers Defence by 10% + 2 and Hitpoints by 10% + 2 (all numbers rounded down). The potion also restores around 10% of the player's prayer points.

This potion is frequently used in conjunction with Restore potions to raise lowered Defence. Contrary to popular belief, this cannot be used in conjunction with a Saradomin Brew to raise all four skills as they will cancel each other out.

Note that Zamorak brew cannot be used with the Lunar Magic spell Boost Potion Share.

People sometimes use this potion to lower their hitpoints.

With level 79 Summoning, it is possible to use Titan's constitution scrolls in order to effectively counter the negative side effects of the Zamorak Brew.

Production costs
The data in this table is based on the Grand Exchange prices of the Vial of water, herb, and secondary ingredient(s). It is accurate assuming all three items are bought off of the Grand Exchange and the resulting potion is sold afterwards.

Trivia
It is possible to make a graveyard by having several people drink several Zamorak brews, thus killing themselves and making a gravestone. Players may then plant flowers around the gravestones to get 'in the mood'.
