There is,
Topic Dungeons under the Picture of the four chests.

On rare occasions, a fourth treasure chest may appear upon defeating the last boss of the Labyrinth of the Ancients. This fourth treasure contains a Dimension Blade fragment that can be used to create the Savage Arc of Triumph furnishing.
Should this fourth treasure chest appear, all members of the alliance are allowed to cast lots.
* Players can only obtain one Dimension Blade fragment per week.

This is all that it is written. No mention about it affecting your weekly gear rolls. But, seeing as every other patch note includes that notice, I'm assuming that it does.
