Thanks for the idea. I've implemented a new key/button that toggles on or off your swinging at enemy monsters, so you can turn off your side of the combat if you're engaging a monster you don't want to kill (though they'll keep hacking at you). Will be include in the next upload in a couple days.
Sounds awesome! Would it be too much to make a per monster configurable option or something? So maybe for example its default settings are set not to kill monsters in the categories which your god will hate you for killing?
