Hello, ive not long returned to wow and i would like to do the mage tower prepatch. However i feel pretty silly as for the life of me i cannot work out what im missing to allow me to start the challenges. i did some of the broken shore when i first returned then headed off to Argus. could someone give me a ELI5 answer please? if im missing a quest or something could you please provide a link to it? <3

When i talk to war councilor victoria i only see this message: https://ibb.co/hWkcu8

This is the current state of my artifact (druid tank)

Many thanks for any help!
Rykuu.
