Sap Strength is an Ancient Curse unlocked after The Temple at Senntisten. It is used in the same way as normal prayers, except you must pray at the altar beneath the Varrock Dig Site to be able to activate it.
When activated and in combat, this prayer will lower the damage of your opponent's melee attacks by 3%, increasing to 9% over time. This is lessened to 2% to 6% in PvP.
For players with a lower prayer level this curse is useful in both PvP and PvM to lower a melee using enemy's stats considerably, however this comes at the cost of prayer points.
