The Quest for the Red Lyrium Reapers is a minigame available on the Dragon Age: Inquisition website. Completing the game will unlock the Red Lyrium Reapers Weapons Pack promotional DLC for Dragon Age: Inquisition.
In the game, character trailers for Vivienne, Iron Bull and Varric Tethras as well as the Inquisitor in The Breach trailer are played. Afterwards the Inquest version of the trailer will become available.
Throughout each inquest trailer are 3 hidden Inquest Elements which must be located and clicked on. The elements appear as a small field of green mist hovering over a part of the screen.
Each time the player clicks on a hidden icon, an image from Dragon Age: Inquisition and audio of a codex entry will play. Once all 3 hidden elements have been found in the trailers for Vivienne, Iron Bull and Varric, the Breach trailer featuring the Inquisitor will unlock.
Vivienne's Inquest Edit
Iron Bull's Inquest Edit
Varric Tethras' Inquest Edit
Inquisitor's Inquest Edit
After watching the Breach trailer, the inquest version of the trailer will become available. At three points during the trailer, a discovery bar will appear above the trailer index scroll bar at the bottom of the screen. Above each of these extra discovery bars, a small green orb icon will appear and quickly disappear. The orb icon must be clicked on. Once clicked on, the icon can be dragged back and forth across the extra discovery bar, frame by frame. By dragging the icon, the player must locate the exact frame which contains a hidden Inquest Element.
To acquire these weapons in game the player must first reach Skyhold. Once reached, the mission to "Acquire the Arcanist" will appear on the war table. Accepting this task will reward you with the Red Lyrium Reaper items.
