Diplomatic Leader (3.5e Trait)
From D&D Wiki
You are a born leader, able to lead your comrades into battle, but you prefer to negotiate for peace.
Benefit: You gain a +1 on your Diplomacy checks. If you have the Leadership feat, you gain +1 to your leadership score.
Drawback: You have a -4 penalty to Intimidate checks.
Roleplaying Ideas: You value life, even those of your enemies. You would prefer to capture your foes, disarm them, or allow them to retreat. Since you obviously can't talk everyone out of a battle, this does not mean you cannot kill when necessary.
