Radiant energy is a type of energy associated with the Divination skill. It can be collected from Radiant wisps randomly appearing during Dungeoneering at level 85 Divination. Each harvest of a Radiant wisp yields 10 Divination experience. Radiant memories can be converted to Radiant energy for 1 experience each, 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 radiant memory and 5 radiant energy can be converted for 47.5 experience. Enriched memories do not appear in Dungeoneering.
