Q:
Lost my Druid ability after update
A:
Did you use the insta level 80 item that showed up in the shared inventory spot? Then you teleported to the silverwastes and used it again to accept the gear and items?
Can you select the Druid traitline in the bottom line? If not, It sounds like it initiated a bug when you used it and locked you out. Definitely report it as a bug and have someone check it out.
Ashen Mistwalker: WvW Tank/Crit Revenant
Oaken Earthlore: WvW Medi/Bunker Guardian
That looks like a bug, you should post that in the bug forums. Try posting on the gw2 reddit for help too, it’ll get you more attention at least.
Do you have the druid traitline equipped though?
When you use the item it asks you if you want to have the game reassign your traits into an Anet-made build.
Check your traits and reassign the druid traitline, which will allow you to use staff.
Thanks you all. Affter speack with a Quartermaster in Silverwastes and make it set to default, its come normal =) Now my druid ability is back)
