So just some d&d inspired ideas.
-I would love an origin that toggles so I could deal nonlethal, maybe have your autoattack do nonlethal with an 80% accuracy (kind of like the -4 you would have in dnd). (I really just dont want to hurt the doggies, also I feel like as a lawful character I shouldn't always kill on sight, though, I also imagine you would be lawful stupid to try to convert any member of the 4)
-I personally love the little tweaks you can do in a table top game, just spending an afternoon dreaming up a person, and then giving them little things, maybe you were a field worker, so you might get a +1 to farming or something similar
-The life blood of fighters, maybe this could be a vindicators wheel house. Or maybe you could have feats to incentive crafting on your main adventure and not on an alt. Like "if you wield a sword you smithed you get a +N% bonus to hit." maybe it would be better worked into traits. Maybe they would need drawbacks as to not increase power creep.
Thanks for hearing my 2 cents
