Insignia are prefix upgrade components applied to armor that are available for armor sets crafted in all campaigns and the PvP Equipment panel as well as Hero armor. Insignia provide bonuses to armor sets; For example, the Radiant insignia adds extra energy in addition to the base statistics of the armor. Max armor obtained from collectors does not accept Insignia. Insignia are available from Rune Traders and can be traded with other players, however the only way to unlock new Insignia in PvE is to identify them from 'salvage armor'. PvP characters can create armor with Insignia in the PvP Equipment panel regardless of campaign, like all PvP items, this armor cannot be salvaged.
Like Runes, Insignia have fixed value bonuses - there are no "non-max" Insignia.
