After you reload and respawn inside the arena he will not aggro when you take the clothes, you can even shoot him with arrows. But if you just wait without reloading he will aggro if you attack him or take the clothes. (at least he did so while being online)
- I did the waiting offline, quit the game, then logged in and reloaded, and spawned inside. Warped back to the bonfire to try something else.
- Then i tried to just stand and wait (online), and picked up her clothes without reloading, but he aggroed. I then quickly reloaded after he attacked once, and he was docile again.
After you have done the reload trick:
- If you just go down to the fog nothing happens.
- If you go to the fog after you take the clothes, he will come running once you get there.
- Maybe you have to wait, then go down to the fog (instead of reloading), go back and take the clothes, then back to the fog again.
I'll see if I have another character I can sacrifice. Taking the clothes prevents more experiments, so I'll try to attack him instead.
