A Barberic problem

[Alphabet555]

I need to know how to raise my inteligence without buying expensive items. I am a barberian, and I cannot use tools. I have 5 scrolls of using tools, but every time I use them it says "Failed to learn the knowledge of scroll of using tools. I am at level 3 with 3 inteligence. I cant use tools, so I can't make food, and monsters almost never give me food. I die, and lose exp making it harder for me to get food, which means I starve more. How do I raise my inteligence level??? Please help
