It’s called tppk, and I haven’t seen one attempted yet in d2r, but I could be wrong
Yeah, that.
As far as I, there was always the risk to get your account banned and having your game key removed (, which I didn't hear happen at all).
What I'm curious about is, if it is still possible, or if they added a timer for how long you need to be in town to turn hostile. One second would be enough to remove that exploit.
Thanks for sharing your experience.
