Buy RS3 Strength flask (6)

Description

The Strength flask (6) is a potion flask in RuneScape 3 that holds six doses of strength potion. Each dose you drink raises your Strength level by 3 plus 10 percent of your level, rounded down. That extra Strength helps you hit harder in melee combat, so it is great for training, bossing, and slayer tasks.

A flask holds six doses instead of the four you get in a vial. That means fewer inventory spots used and more boosts per slot. This is a big help on long trips where every space counts. After all six doses are gone, the flask shatters and disappears.

This is a members only item. It is tradeable, noteable, and can be disassembled. It weighs 0.06 kg. When disassembled, it can give delicate parts, organic parts, crafted parts, enhancing components, and healthy components. Only the full six-dose flask can be traded on the Grand Exchange.

Making these flasks yourself takes work. The flask is made by blowing robust glass, which needs level 89 Crafting. Buying the finished Strength flask (6) skips all of that and gets the boost straight into your inventory.
