Barter - I doubt it's useful. U usually find enough items to sell, plus the items u find on monsters are usually better.
Charm/Intimidate/Reason - I doubt it's useful. I got 100% effectiveness by putting 1 point in reason and selecting reason all the time. First of all it seems you need only one skill, plus you need a very low skilllevel to be effective. I didn't try the 0 points options, but I wouldn't be surprised if they would work as well.
Charisma - Not sure what this does, but seems useless? Or does this actually help with quests?
Leadership - Looks useful, but not sure what it does, what will be boosted.
Lucky charm - seems very useful, when I played Might and Magic Heroes 6 I know Luck is one of the most important skills to be had, I don't know how high the effect is. For now it seems good to put this on your main character (warrior) and put leadership on your secondary character (wizard).
Another skill I want to talk about is from survivor tree.
Lockpicking - Doesn't seem usefull in alpha, I never encountered a chest where it said: 'you need higher skill lockpicking'. Maybe my lockpicking skill was always high enough?, did someone find a chest he needed higher lockpicking for?
