Extreme strength

Extreme strength potions are made by players using the Herblore skill. They require a Herblore level of 89 to make. When a player drinks the potion, he/she will get a 5-26 Strength boost, depending on their current Strength level.

A Super strength potion (3-dose) and a clean dwarf weed are the ingredients required to create this potion. Making this potion will give 230 Herblore experience. The potion cannot be made with the assistance of others.

This potion, along with a Extreme attack, Extreme defence, Extreme ranging, and Extreme magic, can be used with torstol at 96 Herblore to make an Overload potion.

When first released, the Extreme and Overload potions could be used in PvP situations, but within 48 hours, this was changed so they cannot be used in any PvP situation, dangerous or safe, however as of 17 November 2009 Overload along with all other untradeable potions can be used in safe PvP activities.
