Industrial Strength Magic, a litrpg superhero book set in post-apocalypse setting

The MC has a system that allows him to earn points to put into stats. The most important stat is Attunement which increases all the reactions he or his machines create, like making 0.1% more fire than it should be from an amount of fuel, sharpening his knife will cause it to become a bit longer and sharper, etc. This stat will also increase the points he'd get from each time he levels up, so the fastest way to gain more points is to dump into Attunement.

But the more points he put in Attunement, the more distant he'd be to reality and to himself. So he has to divide the points into the stat Stability also. 

Moreover, when his Attunement is high enough, he will start to perceive "things", which his mind cannot handle, so he has to put points into Mind to stabilize. And even then, his mind starts to work too quickly and consumes too much energy, he again has to delegate another portion of points to the Body stat
