I started a new character, which is at level 28.
I decided to respec. Despite spending all available skill points, the main screen comes up with the pause menu symbol and text “Unlock Action Skill”.
Have respecced again, save quit etc, bug still persists. Cannot summon Iron Cub.
You need to choose a weapon. Go into one of other trees and pick any.
Thanks for the reply. I can’t believe it’s that simple. I kept looking and looking and couldn’t figure it out. Thanks again.
