Alts that have not yet reached Level 70 can now complete quests for Spark of Ingenuity on live servers.
The crafting reagent is used in Professions to craft high item-level gear, but the amount you can get is limited. A new quest will pop up every 2 weeks, which means you will be able to get your second spark during the week of December 12, 2022.
The initial quest can be picked up in Valdrakken. The exact location is highlighted on the map below.
