How do I change the behavior of enchants for weapons and armors?

I found the amount of patk/matk each successful enchant level gives on a weapon,
but I cannot find what handles whatever happens after a success or a fail.

Like if I want to change so that instead of breaking on failure, the enchant level decreases by a certain amount.
Where should I look?
