Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - General How skills should have been done.

Most weapon skills are unimportant. You will end up using the Tenebrium skill and your characters will do plenty of damage without these skills.
Armor Specialization is unimportant because it does not keep up with enemy damage.
Shield Specialization is unimportant because tanks are not necessary in this game.
Barter is unimportant because you will be swimming in gold halfway into Act I.
Charisma is unimportant, because it only takes +2 from Traits/Gear to start with 5 dots in Rock/Paper/Scissors. Nothing short of 10 dots will make any difference to how many games you need to win.
Blacksmith, Crafting, and Loremaster are unimportant because you can have a henchman do all that.
Lockpicking is unimportant because you can break everything in under a second.
Pickpocketing is unimportant because there is almost nothing important to pickpocket that cannot be solved another way, and you do not need the money.
