Redhand doesn't achieve its goal that u want it to. the fact u can ko yourself and or simply boat in the opposite direction of anyone that could possibly gank u completely makes redhand irrelevant, so my idea is to simply remove redhand from crime and place it in to combat. if the perp gets aggroed by anyone holding the crime scent in their hand they are given x minutes of redhand based on str vs str (the stats can be anything). this combined with scrying should allow for a proper chance at apprehending criminals with out inconveniencing them.
could potentially add a lot more interesting features to this but that's up for debate, like u leave no scents against these targets etc.
