Shade said:I'm fine with granting Amduscias a bonus similar to what Shroomy suggested, but we're still gonna have to face this with the other Dukes....
....If you really want to give them all some other type of bonus, insight would be the best choice since that is what the BoVD versions of the archdevils possess.
Shroomy said:I think it would be best to play it by ear. The the dukes should all have natural armor bonuses in the +20-25 range (and higher in some cases), but there is going to be plenty of variation. I'm sure some of the available descriptions will mention higher dexterity, armor, and shields, which should account for some of the AC. Especially cunning dukes should probably get an insight bonus, especially beautiful or charismatic a deflection bonus, especially vile a profane bonus etc. I think some flavorful supernatural or extraordinary abilities would be a good way to proceed from the 1e description to the 3.5e stats.
Aspect of BOZ said:I could perhaps even more easily see a Wis-based insight bonus for all.
