Brilliant energy is a type of energy associated with the Divination skill. It can be collected from Brilliant wisps randomly appearing during Dungeoneering at 80 Divination. Each harvest gives 9 Divination experience, and Brilliant memories can be converted to Brilliant energy for 1 experience, with the exact amount of energy per memory depending on your Divination level. Unlike the surface counterparts, these cannot be traded to other players.
One brilliant memory and 5 brilliant energy can be converted for 43.7 experience. Enriched memories do not appear in Dungeoneering.
