In "\common\character_interactions/ms_contract_assistance_interaction.txt

line 22 between the "OR" area here you can insert the conditions that are necessary to use the "contract assistance interaction".

Or 510 if you insert an "OR" there. For the request.

In this way you can add other conditions such as personal characteristics or decisions that have been made.

If you want to give other traditions the ability to perform these interactions, add "unlocks_contract_assistance_interaction = yes".
as another parameter as in
common\culture\traditions/ms_combat_traditions.txt line 18 to the other tradition.
