Guild Wars 2

What’s at the Temple of Melandru?
Haven’t seen a chest… is there one?
Anything else we care about?

Yes there is.
The chest will spawn only after retaking the temple – not defending. Also, it, like grenth, will spawn after the “defend x” preceding event is complete.
You may read people in chat requesting that people let the defense of temples fail, that is why.

The Chest spawn on the event after you defeated the Priest (The one you have o hold against horders of risens for about 10 minutes).

I heard DEFENSE events don’t award a chest, thus why people rather let the risen take the temple/arah gate to ratake it for the chest.
