  • 200 Influence for collecting all 12 pieces


Recovering every piece of the mosaic and letting Gatsi translate it unlocks Codex entry: The Mason's Tales: The Archdemon.


After collecting all 12 pieces, one piece can be missing from the mosaic displayed on the wall at Skyhold. You'll still be able to talk to Gatsi to receive the codex entry as if the mosaic is complete however. (PS3) (PS4) (Xbox One) (PC)
