Tactful TacticianEx
Level 9
Add Diplomacy to your list of soldier class skills. You gain Coordinated Shot as a bonus feat, and you can choose Charisma instead of Strength or Dexterity as your key ability score if you choose the commander fighting style as your primary fighting style.
Starting at 7th level, whenever you gain a gear boost, you can instead select an envoy expertise talent. You count as having expertise with Bluff, Diplomacy, Intimidate, and Sense Motive for this purpose, and you can select only expertise talents that require expertise with one of these four skills. If an expertise talent would require you to forgo your expertise die, you must instead spend 1 Resolve Point to use that talent.
