Think of Luck in SMTIV like a Charisma stat, because it makes negotiation easier. It has a lot of other effects like Smirk rate. If you're going hard into Luck, you should also go hard on spending your App Points on recruitment and fusion skills. Even if you completely fuck up Flynn's build, there's nothing you can't accomplish with the insanely overpowered demons you'll be able to create.
