Yeah, I noticed that one. I was testing to see how the game calculated melee and ranged hits, like some are talking about now. The bite attack seemed to have a built-in 3 yard range or whatever you measure range in, where you would still get hit even with some space between you, but once you go past the threshold the attack would miss. You would not have to do a double-tap dodge to avoid the attack, so I guess it's like an invisible AOE attack. But a good bit of the time was also the wolf trying to even face me.
I was trying to see how many of the attacks in the game you could juke or dodge like in Skyrim. Ranged definitely does the curved bullets thing, but melee had a few you could dodge. Not like it helped though, since the AI would always run straight for you and not worry about its own preservation.
Kill swamp things until you get 3 branches, kill pirates until you find the widget, kill bandits to get 3 items off of them, kill wizards to get 4 stones... The game was full of them where I was playing.
