Not from the gem store, the Wizard's Vault. The daily system has been replaced. Currently there is an option to buy a legendary starter kit. It contains a limited set of legendary sets (there's only 4 to choose from), that give you the Precursor weapon, the weapon specific gift, and a random Gift of Might or Gift of Magic.
It's a really great boost for crafting a legendary weapon and worth grabbing. I'm now about 500g away from my next legendary weapon and I literally just finished one a few days ago. It's going to take a while, but it's exciting stuff!
I think Valdhertz bugs because people stomp through it too quickly and kill things before certain internal events get to run, stalling the entire thing. Completing it yesterday with one other person and thankfully we successfully completed the daily.
However, adding an additional option is a good idea and I look forward to it, as there are objectives I've not wanted to do.
