Currently the series of achievements that you get from completing 1/10/50/100 pledges given by Urgarlag Chief-bane are listed under the Dungeons: General category.



However, since Urgarlag only gives daily dungeon quests for the DLC dungeons, I think these particular achievements should be moved to the DLC sub-sections. This would be in line with the previous changes that were made to the IC dungeons when they first came out; all of the achievements associated with WGT and ICP were moved from "Dungeons" into their own special category, and all of the Hist dungeon achievements followed suit.
