Lodestone was a subcategory of the Exploration category which was released on 13 March 2012 alongside the Lodestone Network update and was removed from the game on 2 November 2020. It was split up in the Free to Play Lodestones and Members' Lodestones subcategories within the Exploration category.
Prior to 18 April 2017, this subcategory was known as Lodestone Network Tasks. On 6 March 2013 a new set of lodestones were added with corresponding achievements. No skill or quest requirements are needed to complete the tasks other than the quests or skills required to access the lodestones.
