The Kingfighter script is pretty awesome. I love how it can loot specified items, bury bones, and pick up arrows. I appreciate your work in building it.
Few usage anecdotal notes on my experience
I have found that the save button for saving new configurations doesn't reliably work. I think I'll try just editing the *.ini files to get all the setting I want in there.
I have also observed that after running the script for longer than ~10-20 minutes that the monster killing slows down. Specifically it stops making the decision to start attacking a new monster. Note that I'm using it in the Waterfall dungeon but I do not have the dungeon specified since it's not in the drop down.
