Title - is there a list of all the legendary properties available on wizard ethereals? I’d swear I had Aether Walker during PTR but no dice so far. Is my memory faulty or luck bad? 
Aether Walker can spawn. I have it on a Wizardspike:
I don’t know if there’s a formal list anywhere, but on D3planner - Maxroll.gg - Diablo 3 Resource Website Season 28 if you equip a Wizard ethereal and then go to switch the legendary power on it, it lists all the options that are available. There’s 19.
