Dragon Age III: Inquisition Message Board  

First activation of the switch near the construct in the center of the room activates the archer to show you what it does as it lights up the first thing. This will need to be done for each direction as the archer rotates clockwise and shoots on each pull. You simply need to move the pillars out of the way momentarily.

Second pillar you need to pull that first lever near the door you entered to open one of the gates at the side of the room. Now you have access to 3 torches. You can either do them quickly in succession, or select each member and 'hold position' near each to make it easier.

Next you have to have one of your members stand on one of those elven plates (in one of the corners of the room) and hold position.

Then the final one requires you to activate two levers that are behind the gates on either side of the room. To access both, you need to have someone hold position near the gates that switch on either side, namely where one of the torches you accessed on one side, can't remember where on the other. Then have one member activate that first lever (near where you first entered again) to switch the gates back to their original position to give them access. Each party member then activates each switch and that should light up the last tree-thing.
