Overloads

Error creating thumbnail: Unable to save thumbnail to destination

Overloads are potions which combine the boosting properties of all 5 extreme potions. They are created by combining 3-dose extreme attack, extreme strength, extreme defence, extreme ranging, and extreme magic potions with a clean torstol. The process grants 1,000 Herblore experience and requires level 96 Herblore, which can be boosted but not assisted. Four empty vials are left over.

This potion can be made into an overload flask by using at least six doses of it with a potion flask. Players do not need a specific level to turn potions into flasks.
