Bandit's brew

Bandit's Brew may be bought in the Bandit Camp (Kharidian Desert) for 650 coins. It raises Thieving by one. It also raises Attack by one and decreases Strength and Defence by six. However, it cannot be used to circumvent the minimum Thieving level requirements of certain quests such as Rocking Out or Desert Treasure. Some players might not consider buying this ale, as the price generally isn't worth the benefits. Bandit's brew cannot be made using the Cooking skill.

Players must buy one during the quest Desert Treasure before the bandits will talk about the Diamonds of Azzanadra.

The Magpie and Abyssal lurker familiar can raise thieving by 2 and 4 levels respectively, making this item less popular by comparison.

Players cannot make a Barrel of this in their Kitchen, which may be another reason for its lack of popularity.

Trivia
The Bandit Brew looks like a normal Beer, only a slightly darker shade of orange
