maraudon instance

hello guys i would like to ask some informations about this mara runs i make the bother to make links for everything so it can be readable and easier to respond so enjoy.
here in this site below i linked says : the first half of the instance is where you will find and complete the quest that rewards you with the Scepter of Celebras. Right-clicking the scepter will teleport you directly to the 2nd half of Maraudon
so my first question is if u have the Scepter of Celebras can u keep using it more than 1 time or is it disapearing after the first use
