Hello,
I recently completed the Chain Quest to be able to summon Anzu mount in Sethekk Halls.
The problem I have, I killed one the boss Anzu I was able to use the item that Mathias gave me from Zangarmash but after that I was not able to take anymore the quest from him to REsummon the Anzu (next day). Can someone explain me how to make it to obtain that item from Mathias to summon Anzu ?
I repet Mathias don't giev me any quest anymore.

Thanks you
