I can't get into the inner wolf den to kill the alpha. It keeps saying I'm not ready. What do I need to do?
Just fight 2-3 random werewolves doesn't matter how the fight with them ends if you win, lose, submit or fuck them you just need those fights to lure the werewolf alpha. If you're talking about the dire wolf(normal) alpha just go to the skull at the top right you'll fight three wolves there the middle one is the alpha
I think he meant entering the door in wolves den. I think you need to encounter Logan being angry at night. After he left, check again the den. You will see that there is a mark right below the door. After that, you can enter the door and fight the beta wolf then alpha wolf. (Logan is having revenge after being converted to a werewolf)
