Are there any glitchless runs of this floating about anywhere? I was thinking about doing one, but the more I think about it the more time consuming I think it'll be. Can't seem to find anything through our friend Google.

Plus tricks such as selling/stealing for gold with potions would be out. How long would this actually take?

There was a back and forth about it between Smilge and Jiseed once upon a time. I think Smilge had compiled some notes for it as well. As I recall, rescuing Hendak was one of the absolutely mandatory parts about getting through chapter 2 in a hurry. I keep flirting with the idea of routing it myself but I can never seem to find the time. Optimized I'd guess it's probably about a 90 minute run glitchless?
