Lustrous energy is a type of energy associated with the Divination skill. It can be collected from Lustrous wisps randomly appearing during Dungeoneering at level 70 Divination. Each harvest gives 8 Divination experience. Lustrous memories can be converted to Lustrous 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.
