Emblems are special Avatar items that can be embedded in your Avatars with sockets for additional stat bonuses.
Emblems are available for purchase from NPC Daphne Marbros. However, you may Sunder your avatars for a chance to obtain a random Emblem that is not available from Daphne. To Sunder your Avatars, talk to Daphne and select the Sunder Option.
Please take note that you cannot Sunder Mileage Avatars.
