just put it down to six.
I don't recommend to put 6 in INT (based on all post where INT is the subject), unless you know what you do ! Take care of any malus.
All other attributes are needed, if you put int too high and you don't play a caster you'll have problem with you're other stat attributes to strike at melee or at ranged attack or to move fast or to regen your life or to be able to take damage ...
=> If you learn "fast" (relatively to what we know, it take probably many month of gameplay) all skills and couldn't use them at fullest it will be damageable.
