Penance horn

n receiving double experience from a skill task, the Penance Horn will lose some of its charge. The charges can be regained byamount of charges it had before it was lost. The horn does not need to be taken in to the activity to obtain charges.

At least 10 cycles of waves are needed to charge the horn fully if a player does waves 1-10. However, some players prefer to do waves 1-5, which fills the horn after 36 cycles.

Agility
The XP reward can be spent by completing agility courses, excluding the Werewolf Skullball, Agility Pyramid and the Penguin agility courses.

The completion of any wave fills your horn by exp based on the point total for that round, averaging around 100 waves, or 10 rounds of all 10 waves, for a full horn. It's widely debated whether doing the entire 10 waves ten times is faster to fill the horn - it's also possible to fill the horn by simply doing wave one 100 times, since the bonus for doing higher waves may or may not apply to obtaining potential. Doing waves 1-5 is recommended if using this method.

NOTE: As of 11/04/2012 the horn has been updated to display a percentage of potential. Please submit data on the talk page.
