you never forget your first (class: Reformed)
Design note up front this time: This class really doesn't make sense for games where resurrection or a positive afterlife are achievable. Which is a lot of games. Sorry about that.
Special: You can't start as a Reformed. Levels you take in Reformed don't count towards your level limit. You can't take levels in other classes while you have Reformed levels. (However, at X, you get the ability to lose your Reformed levels whenever you want.)
W: Stained; Oath of Nonviolence
X: Cautionary Tale; Shadows of the Past
Y: Swords to Plowshares
Z: Redeemer
Stained: Any attempt to trick you by appealing to your better nature fails. You know the truth.
Oath of Nonviolence: You cannot try to kill anyone. If you aren't fully certain that an action would not count as trying to kill someone, then you can't do it. That also goes for whether an entity counts as "someone." Allies who train with you for a day can embarrass opponents at 0 HP instead of killing them. Your own bloodied hands can't be trusted to do it, though.
Cautionary Tale: Your words of warning have a [Reformed templates]-in-6 chance to talk down anyone who's yet to take a life, in addition to whatever other resolution mechanics might exist. If you pay someone to walk away from a fight, gain XP equal to the gold you spent.
Shadows of the Past: If an ally chooses to kill, gain a point of Tension if you find out about it (or if you choose not to find out). You can resolve this Tension by going back to your old ways. If you do, lose all your Reformed templates and Tension, and attack, making an extra attack for each point of Tension you lost. If you don't, you need an extra hour of sleep each night for each point of Tension you have. Because of the nightmares.
Swords to Plowshares: Any magic weapon that belongs to you, you can reforge into a tool. As a general rule, +1 gets twice the work done in the same time, +2 is three times, and so on. If you don't know ordinary blacksmithing, you'll need to learn it, but the power of your resolve enables you to work anything, even evil sentient weapons (which are defeated by doing this).
Redeemer: There's a nonzero chance you can get through to even the absolute worst "someone" who exists. I won't tell you your odds. I will tell you that if you ever give in to Shadows of the Past, they do too.
Design notes: I'm on the fence about whether Reformed who go back to their old ways should keep the HD and HP they gained as Reformed. I think it's probably fine because Reformed locks you out of a lot of your previous class while you have it, and to go back to your previous class you have to lose it. But it might be kinda stupid with some classes. Particularly utility mages I think.
This is obviously meant for warrior or assassin type characters though. Specifically it's riffing on episode 3 of Xena, Warrior Princess, as well as countless player experiences I've heard regarding Paladin classes. If I've done my job here, this class is not so good that you'd want to force your character to try to be penitent just so you can play it, but if you're already feeling weird about the slaughtering then you can use this and have a good time.
