Tried this script and worked OK on test account. Total completion time was 9:49, but I had to manually intervene twice:
Towards the end of the island. When trying to range attack the rats, script went into a corner and got 'I can't reach!' dialogue until a rat was finally in range and killed. The script never closes this dialogue ("I can't reach that"), meaning once the script arrives at the poll both segment, it continually spam clicks the poll both, since it cannot continue the poll both dialogue, since the previous "I can't reach" dialogue is never handled and still shows. I had to manually progress through this dialogue.
The script runs flawless from that point up until the Wizard/end segment, where it non-stop attempted to attack chickens through the gate (with the bronze sword), instead of trying to cast Wind Strike on the chicken. The mage book WAS opened during this, just Wind Strike never selected. This may be due to the fact I ran the script in resizable/modern layout.
Will fiddle/test some more (once I am home and have access to a VPN), may have just been bad luck. FWIW, I was only charged 9 cents (the correct amount), compared to other reviewers claiming they were overcharged: not the case here.
