I had a bit of trouble finding a "list" of positive character traits that could serve as a quick reference when one intends to quickly beef up a few characters on thier campaign map.

With that being said, here's my quick list of positive traits by character type. I have not added comments to all of them, but I can tell you that i've avoided traits that have ANY negative affects (in some cases by only noting the highest level of a trait that can be acquired before negative affects begin to occur).

How to use:
1) select the character that you'd like to add traits to.
2) type something like this - give_trait this GoodAssassin 5
