Sap Summoning

Sap Summoning is an Ancient Curse unlocked after Temple at Senntisten. It is used in the same way as normal prayers, except you must pray at the altar beneath the Digsite to be able to activate it.

When activated, this prayer will randomly your opponent's summoning points by 10% while you are in combat, and over time this drain will increase to 20%.

Note that this curse has no effect against enemies that do not use summoning. This only works for enemies that summon creatures.

Trivia

 * This is an often overlooked ancient curse due to the fact players don't see very much usefulness. In fact, if used right this can be a very effective prayer.
