Zamorak brews are made by mixing torstol and then jangerberries in a vial of water, giving 175 Herblore experience. It requires level 78 Herblore to make.
Zamorak brews temporarily raise Attack by 20% +2, and Strength by 12% + 2. It also temporarily lowers Defence by 10% + 2 and remaining 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.
A Super strength potion will always boost Strength level higher than a Zamorak brew; however, the Zamorak brew's attack boost is slightly better than a Super attack potion. At levels 85, 86, 90, 91, 92, 93, and 95-99, the Zamorak brew will give a boost of 2 levels more than a Super attack potion. You can also use a Super strength potion or a dragon battle axe special attack before you sip a dose to increase your strength level to the max.
Note that Zamorak brew cannot be used with the Lunar spell Boost Potion Share.

Trivia
- Due to all of the disadvantages of this potion, it is rarely used.
- The extra attack bonuses of this potion can be beneficial to teams of 4-6+ players killing the Corporeal Beast, as a single dose can be used before fighting and the player can replenish/boost other stats.
