Trait-based Action/Behavior Resolution

Trait-based Action/Behavior Resolution
(Inspired by Pendragon RPG trait system)

Perhaps this might help guide some NPC interaction in your solo play.

I originally used this to help determine alignment-based actions by NPCs using B/X D&D. It should work well using any trait that has negative and positive extremes. (Lawful, Honest, Brave, Loyal, etc.)

Assign a trait value of three (most negative) to eighteen (most positive) or roll 3d6.

When it is unclear how the character will act based on the trait, roll a d6 and apply the trait value's modifier.

A result of three or lower indicates negative action, a result of four or higher indicates positive action.

Characters with trait values of three or eighteen will always act negatively or positively to some degree unless there is unnatural influence.(Fanatics!)

TRAIT VALUE • MODIFIER
3 • - 3
4 - 5 • - 2
6 - 8 • - 1
9 - 12 • 0
13 - 15 • + 1
16 - 17 • + 2
18 • + 3

Adjudicate the magnitude of the action or base it on the roll result, such as:

Less than 0 • extreme negative action
0 - 2 • negative action suitable to circumstances
3 • minimal negative action
4 • minimal positive action
5 - 7 • positive action suitable to circumstances
8+ • extreme positive action

Cheers!
