On the other hand, though, I feel like Havel’s massive armor and dragon tooth club are a sign that this guy is dangerous and you shouldn’t just rush in and fight him normally. He has basically only one attack, so if you take a few moments to study him you can learn the timing of it and if you’re careful you can avoid getting hit at all.
He’s also potentially the first aggro human NPC you see, I think. I used the master key to open the door my first time. Thinking “hey, there’s a dude just chilling down here behind a locked door. Maybe he’ll have something cool to say or give me something neat for letting him out!”
