When I play D&D I at times try to spare enemies I fight because I don't believe in going ham on a few poor thieves that are just trying to get by by robbing me, or killing a guy I had a disagreement and a few thrown out curse words with. I haven't gotten far enough into the story to really find an option for it yet but is there an option to not kill enemies and instead just knock them out after a fight? If not I think it should be added. I think it would lead into interesting dialogues or maybe different quest lines, such as a mad woman running up to you and because you knocked her out you realize she was being mind controlled by an evil wizard just nearby.
It's something small but I think it would add a bit more to my characters personally because I always try to be a "goody two-shoes" when I play D&D.
second row, second to last button. looks like a mace and person, it's just to the right of dash.
Turns your damage into nonlethal (watch out for spells like hex, or things doing additional damage) uses unarmed strikes or near enough damage. Best way to do it is get them within 10hp or so, then just have every melee them with this button pressed.
added because I'm an ass. Look at each button on display test them out see what they do, hover over them. Part of being in EA on any game is trying all the little things you spy with your opened eye. and though I am guilty of oops, went to forum to soon.
