Chaotic Archeologists gain alignment for taking historic statues and moving them off-level. Neutral Archeologists gain alignment from bringing historic statues into their quest home. (Lawful ones get nothing, because it’s right for them to leave the statues where they were.)

Differentiate the neutral alignment by making it not really about killing. Instead, neutrals get rewarded for forcing monsters to back down, surrender, and get left alone peacefully. (Sapient monsters will beg or gesture for mercy when brought down to sufficiently low HP; non-sapient monsters will produce some other message). To keep loot fairly balanced, a monster that surrenders will drop its gear.

Your alignment record should shift over time based on your alignment:

• Chaotics get -1 penalties over time for failing to do any chaotic behavior.
• Neutrals get +1 alignment bonuses more slowly over time by not doing anything.
• Lawfuls get neither of these and need to get their bonuses on their own.
• Alternatively, lawfuls accumulate bonuses by doing nothing (not breaking the law).

Lawful and neutral gods should be angered (or do something angry) if you consort with a foocubus on their altars or in their temples.

Lawful and neutral gods should respect any conducts you currently have when giving you stuff:

• If you have been illiterate, they will not give you a spellbook.
• If you have been weaponless, they will not give you artifact weapons (maybe could give a +1 intrinsic damage bonus instead).
• If you have been pacifist, they may send tame minions.

Meanwhile, chaotic gods will ignore these rules and give you whatever.
