Also, his skill is fairly rare.
This part confuses me the most. How it's possible to meet such a level of prejudice to this skill when it's rare and wasn't properly researched?
From the other hand, if it's not so rare, then why this skill is still unresearched?
Again, if it's rare then the author should show us how it's difficult to use it. Without skipping the whole part where MC is using it. What we have now is "well, I will not be using it because this skill is shit. Poor me, the world is so mean. Sob-sob."
It is MC who is shit and not the skill. This is what I think after reading it.
That's not how you write a proper story.
You don't become an adventurer when you disadvantaged. Instead, you should go to cultivate fields and raise livestock.
