Detailed codes for several Console Commands
Push ~ to access the console. As described above, the "give_trait" command works with several different traits to add to a specific character. In order for this to work, you must have the character selected and outside of a town. It works like:
give_trait this TRAITNAME #
Below is a list of TRAITNAMES and the maximum number you can put after to determine the level of the trait. These are a list of the most beneficial traits, message me if you want me to post the more obscure ones.
When your in campaign mode and you move a unit to a selected spot. The unit moves there but walks there and moves very slowly. To speed thjis up just hold down the right click on the mouse and this will speed up how fast the unit gets to where you want it to go. Also this works when your turn is up and the other country's are taking there turn.
Traits
Use the following values with the "give_trait [character] [trait] [level number]" code. Note: Some of these can be accompanied with a "level number", usually ranging from 1 to 5, giving additional bonuses (or penalties).
