My computer here at work takes forever to search/display so I apologize in advance if this has been discussed in length before.
I think alignment change is a potentially very touchy issue and some considerations could be implemented by the DM involved in PC actions or maybe just on the scripted quests.
I've had my character's alignment changed twice, both times away from lawful. I am not complaining about the actual changes, because it's pretty cool and adds depth to the experience, but it needs to go both ways I think.
Both times they were due to things that my character could not possibly have known about, and therefore were not conscious acts or even avoidable. It puzzles me why an entire party should experience an alignment change by a short brief act of one of its members with no RP related to the change before or after it.
Example - a character in your party insults and attacks another character. The act itself is a chaotic act. The RP of the people around should dictate whether they get an alignment change as well. If a character lectures them about, then kicks them out of the party when they don't listen to it, and makes a report to the Watch, those are some pretty lawful acts. If they laugh and slap them on the back after the fight, that is an unlawful response.
Perhaps it just takes too much time to DM these things that closely, but I would prefer no alignment changes issued at all if they aren't going to go both ways. Or make them affectable by scipted quests so that the DMs don't have to micromanage this perhaps?
If scripted quests already can change alignment (I'm not sure if the one that changed my character's alignment is even still around), then there should be other scripted quests that would counter it. Perhaps there are, but of the dozens of different scripted quests my characters have been on, only one changed alignment .
Any time you do job for the Watch (the Law), I would think it's a lawful act. Sure you get gold for it, but couldn't an option to take half or no gold showing that you were doing it for only the sake of helping the Law be added?
Maybe a couple options on the portal to the surface quest in the Canal Ward....get pissed and kill the guy, chaotic shift. Turn him into to the scripted guard just outside and get a lawful shift. Lots of creative ways to subtly change the quests to allow shifts one way or another.
Maybe these are abusable by peeps trying to affect alignment changes for their dwarf barbarian to get his dwarven defender PrC, or for their pally to become fallen and an evil rogue/assassin/blackguard, but isn't that what player development is all about?
Going from 85 to 78 in the Law/Chaos balance isn't a big deal, but I'm RPing my character to be LG and getting even minor shifts toward that when he is RPed that way would personally be very rewarding to me, and perhaps others.
