Thank you for the script I won the first time, but failing every since. Running sk, mage, mage, chanter, druid, shammy. One mage is the stunner. Set all but shammy to mele. Lucky on the first try that stunner mage was rezed, campfired and made the final boss. Since then one or more casters dies before final fight, rez and runs kinda work (start with none on mele to test but no change). Script engages the final boss and then run to archers wipes group or fails. Thanks again for the effort and my one check mark for completion.
To disable the archer chase - open up the config for your character: config\mission_finalfugue_{charname}.inni
