Extreme strength

Beta

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, they will get a boost of approximately 5 + 22% of the player's Strength level, then rounded down This makes for a maximum strength boost of 26 at level 99.

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 an Extreme attack, Extreme defence, Extreme ranging, and Extreme magic, can be used with a clean torstol at level 96 Herblore in order to make an Overload potion.

This potion cannot be used in dangerous PvP situation. Consequently, it cannot be used anywhere in the Wilderness, except for one or two spaces away from the Wilderness wall, King Black Dragon or Corporeal Beast. This is because these spots are not considered PvP areas. If a player travels to any other part of the Wilderness after drinking an extreme strength potion, the boost will be reduced to the power of a super strength potion.

Production costs
The data in this table is based on the Grand Exchange prices of the potion's ingredients. It is accurate assuming all tradeable ingredients are bought off the Grand Exchange.

* However, the untradeable potion can still be used.

+   =    A 3-dose Super strength is mixed with a Clean dwarf weed to make a 3-dose Extreme strength.

Flask
This potion can be made into an Extreme strength 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, but since all untradeable potions must be made by the player, the flasks actually have the same level requirement as the potion itself, unless of course, a stat boosting item such as Greenman's ale (m) is used to make the potion in the first place.

Trivia

 * When first released, the Extreme and Overload potion(s) could be used in PvP situations; within 48 hours, this was changed so that they cannot be used in any PvP situation, dangerous or safe. However, as of 17 November 2009, Overload (along with every other untradeable potion) can be used in safe PvP activities.
