Speaking of speccing Geralt in a particular way, you're going to want to give up at least three of your points to boost the mind-controlling Axii spell to maximum. Axii is the one spell that matters most outside of combat, as you'll be able to use it in many conversations - essentially to Jedi mind trick'ing your way out of certain situations. The reason this stands out as something to focus on, is because in Witcher 2 you were presented with a percentage chance of this working, meaning even at a low level there was a small chance you'd be able to pull it off - but in W3 it's resorted to a more strict "No level? No chance" setup. Due to the amount of times quests can turn on a dime and Geralt can find himself on the business end of a hairy scenario involving any number of lives about to be lost, it's invaluable to boost this skill and have it ready should the need arise.
