Ok heres the deal. I used to be able to predict him very well. This season though he has been unpredictable...(for me) or maybe I just missed the point every time we have done ancs in any difficulty.

What is Khorlic's AI? Did it change this season? What does he chase after every game? Just highest Level? And, do the other have a similar AI?

No changes have been made to the quest AI parameters passed to the ancients or for that matter their their overall AI type. What I do know for sure about the AI is that it tends to be a preferred target AI where they'll go after the preferred target heavily if they can. As for what particularly determines the preferred target I'm not sure... That's getting into really obscure AI mechanics that Phroezen Keep might be able to shed some light on.

It's not controlled by monstats, the ancients AI is fully hardcoded (thats why it won't work on any other unit than those).
I just unlocked those AI's last week funnily enough so I could have enemies that use WW propperly.

Korlic picks a target completely at random and sticks to it until you break his line of sight, manage to get out of range, get killed or kill him. Once he has picked a unit and lost it (without killing it), if the unit comes back into view, he might switch between current target and previous target.
You need to edit the stuff at 6FCEF7A0 in d2game to adjust his AI params.

hmm so he is completely random??? because ive never seen him chase the actual player chars until this ladder. figured it might of been a lvl or something because the times i have noticed he has chased the highlest lvl in the area. khorlic is a hoe anyway
