Until you have run dungeons
Another great way to accumulate badges is the weekly raid quest, but due to the Tabula Rasa credits, you may not be able to find a spot until you have run dungeons for a while. The entire tier 9 raid set is available through a total of 210 Emblems of Triumph, with each piece being 30 or 50 emblems, but the gear is only item level 232 as compared with the 245 of the rest of the triumph emblem gear.
