A Flicker in Darkness is an achievement that requires the player to use a crater to convert a memory of tier 2 or higher to energy in the starting room of a Dungeoneering floor.
Memories can be gathered from the same type of wisp, which are randomly found in dungeons. A crater to convert memories is located in the start room. If necessary, boosts may be used.
- This achievement used to be a task prior to the release of the Achievements System on 18 April 2017.
