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.
A Zamorak brew temporarily raises the player's Attack by 20% +2 and Strength by 12% + 2. It also temporarily lowers Defence by 10% + 2 and the remaining Hitpoints by 12% (all numbers rounded down). Additionally, the potion restores around 10% of the player's Prayer points. 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.
Restore potions are frequently used with Zamorak brews to raise lowered Defence. A common use for Zamorak brews is when killing Corporeal Beast, where a dose can be used before fighting and the lowered stats restored with an ornate rejuvenation pool. The brews have a slightly bigger boost to Attack than Super combat potions and are cheaper, making them a decent alternative. However, they are rare for general use due to the drawbacks.
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, 90-93, 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 battleaxe 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.
