Word of Censure currently receives no bonuses from any Archon skills, unlike other words. Sin Seer provides no bonuses to any Archon words, unlike other skills.
My suggestion is this: Word of Censure gives a damage bonus against anyone examined by Sin Seer, regardless of alignment. This damage bonus is equal to the square root of the sins declared by Sin Seer. Each successful attack reduces the number of sins declared by 1 (appropriately reducing the damage bonus) to a minimum of 1. This last point can only be removed by the Archon gaining kill XP against the target.
Example:
1 sins named : +1 damage bonus until death.
2-4 sins named : +2 damage bonus for up to 3 attacks, then +1 until death.
5-9 sins named : +3 damage bonus for up to 5 attacks, then +2 for 3 attacks, then +1 until death
10-16 sins named: +4 damage for up to 7 attacks, +3 for 5 attacks, +2 for 3, +1 until death
17-25 sins named: +5 damage for up to 9 attacks, +4 for 7 attacks, +3 for 5, +2 for 3, +1 until death.
And so on.
If the Archon has remaining Censure bonus upon the kill, that is immediately converted to 1 MP/XP for every sin remaining and awarded to the Archon. The bonus and sins are then completely cleared. An Archon subsequently examining the target with Sin Seer will be informed that the target has been chastised for those sins, and those sins cannot be used in any further Word of Censure bonus. Furthermore, those sins will no longer be counted when deciding if the target is blessed (As the target has been chastised).
If the target examined is a demon, the damage the Archon takes is reduced by the number of sins named by Sin Seer. If the Archon has Hand of Zealotry, the demon gains additional "sins" equal to the damage the Archon subsequently takes. This is reduced to 0 if no sins are found, so the rare demon with no sins will provide absolutely no bonus to the Archon while inflicting full damage upon the Archon. A demon MUST have at least one sin to qualify for a damage bonus (and thus at least one point of damage reduction to Sin Seer). That rare demon isn't getting blessed unless they have positive MO, though, which carries it's own problems for the demon.
Despite this, the demon with zero sins COULD gain a bonus of +2 damage, +10% accuracy, 10% defense reduction, and +1 damage floor against angels or members of good factions for five hours out of sheer egotism. It's not *EVERY DAY* one manages to appear blameless before one of those sanctimonious winged jackasses, yanno?
