With the current system a ranger that intends to deliver justice will either marked a bigger criminal (unless he pursues a murderer) than the original culprit (at least for theft) or likely to be barred (through visitor) from taking action when reaching the criminal unless tearing down the whole place, which is somewhat unlikely to do (when avenging anything except maybe genocide).
Thus I suggest the following:
- Carrying a summonable Scent allows circumventing Visitor debuff for initiating combat on the target character, generating a Olfaction of Vengeance instead of Smell of Assault
- KO'ing a character for which one carries a summonable scent generates Residues of Reprisal instead of Stink of Battery
- While having a Reek of Theft in possession the 'Steal' (from the downed target character) generates Redolence of Repossession instead of Reek of Theft - consuming one Reek of Theft with each item that is taken from the inventory/equipment of the target, blocking that particular scent from being used again until the target has recovered from KO (removing that theft crime and any scents collected from it could also do the trick)
- Possessing Stench of Murder disables the KO mechanic of the target character, killing that character generates a Perspiration of Retaliation instead of another Stench of Murder
- The actions above don't need criminal acts being turned on, as they're the opposit of them
- The 'justice' scents are not summonable, while they should give Redhanded debuff (to make it not that easy to get away) they don't impose Outlaw
In before the naysayers:
Yes, being a criminal should IMHO suck more than it currently does and it should be impossible to hide behind visitor. And yes, there could well be good arguments to tweak scent rules to cater faction warefare - but as I'm not involved in that I don't feel the need to come up with something, so feel free to suggest reasonable mechanics that could remove the shortcomings (eg. mass-spamming nidbanes from the scents collected on a battlefield) of the current system for that application.
