Volatile Valuables is an achievement that requires the player to sell some rubium to Ezekial Lovecraft, who is the owner of the fishing shop in the town of Witchaven.
- This achievement used to be a task prior to the release of the Achievements System on 18 April 2017.
- Before the introduction of the Salt in the Wound quest, on the 5 July 2011, the requirement for selling rubium to Ezekial Lovecraft was to have finished Kennith's Concerns, for Ezekial would be present at his fishing shop after completion of this quest. After Salt in the Wound was released, Ezekial would not be seen in his fishing shop after players finished Kennith's Concerns, forcing players wanting to complete this task having to wait until the bug was fixed or complete Salt in the Wound for Ezekial to appear back at his fishing shop. This has been fixed.
