From the wiki:
Intellect: Cognitive ability, speed of learning. It influences directly the strength of your spells, and your magic resistance, critical chance and more 3 maxEnergy points and the damage of your spells by +2.
I don't have proof, but I feel like most of the second sentence is a lie. You didn't specify how it influences these things, but both my magic resistance and critical chance are both 0 with over 70 points in intellect. Speaking of critical hits, I'd suggest explaining what those do somewhere.
You also say it influences directly the strength of your spells and the damage of your spells by +2. Not sure why you repeat that unless strength and damage mean different things, but without equipment, most enemies take about 10-20 damage from all spells. I assume this is a mistake, unless a human thief is supposed to resist about 90% of all magic damage. Or did you mean to say it increases damage by 2%? But then, 2% of what? No spell has some kind of base damage written next to it.
Also, I think the skills "Weakening" and "Precision cut" deal too little damage if I understand their descriptions correctly. Specifically, the description of "Precision cut" says "Focus all your strength...", but I don't think either of those skills scale with strength.
