No, I do not think you would be banned. During development I ran the script for about 40 hours in 3 days for testing, and was not banned(keep in mind the script was pretty barebones and buggy during some portion, as it was in development). I have since run the script 10+ hours a day and have yet to receive a ban. By no means am I recommending anyone to bot that much, frankly IMO that's asking for a ban, however given what I know so far I would think that 3-5 hours is safe.
I could add the option to avoid the chaos druid area and instead go around, but I feel that it would add unneccessary time to the runs since the script is designed to tele back to edge when under a specific hp(Tele hp setting in the gui). I can make it enable run when near the black demons, I actually had it doing it before in one release and I must have forgot to add it back after editing code. I will soon add a guide to filling out the gui. Thanks for your feedback =).
