Notes: The penance horn allows potential experience to be gained in Firemaking (by burning logs), Agility (by completing laps), and Mining (by mining ores). While wielding this horn with potential experience filled into it, double experience will be gained in the above skills. To fill the horn, you will need to play some rounds of Barbarian Assault with the "Experience" reward checked. Checking its potential by selecting its "Check-potential" option won't tell you precisely how much experience is left in it, but will give a general idea of how full it currently is, e.g. it may tell you that it is half-full.

Note that no honour points will be earned while gaining experience for your horn. If you have level 5 in any Barbarian Assault role, you can upgrade your horn to the Penance master horn for free.
