This article is about the magic spell. For the weapon with a special attack called Weaken, see Darklight.

Weaken is a level 11 spell that requires a body rune. It reduces the target's damage dealt by 5% for 1 minute.

Remember, you cannot use Ancient Magicks or Lunar Spells if you are using standard spells.

Monsters such as elemental wizards, dark wizards and catablepons are mystical in nature, and are capable of casting Weaken upon players. This effect does not wear off even if you are logged off, however it will wear off within minutes at most if you stay logged in.

It can be cast again on the same target at any time to refresh the duration. Experience is gained only if it hits.
