Alchemist of emotions.
The more powerful being, the better the effects of the potions MC can create. Simple right?
Except that anger creates strenghtening potions. Confusing them helps with intelligence etc.
So, the only way to improve is to literally beffudle Gods and others just to gain stronger so MC won't be squashed like a bug.
heh good luck

Learn or die
MC has a time bomb on him. The one true way to get rid of it?
Just obtain enough random day to day life skills to live!
Now, how about mastering ancient magics in few days.
Confusing the bald one.
Learning how to craft infinity stones to live a day longer?
Perhaps playing volleyball with Thor's hammer
Endless possibilities!
