I already accepted the levels of mediocrity this story tries to sustain, but it's really underwhelming how the MC is presented as a container of unlimited power, and he only uses "level 1 spells". Even if it's to maintain the harem's image of "strong female warriors", making the MC weaker than he should be, so the girls' have presentable merit, is pretty weak.
This is one of those things that really surprised me that it sold at all.

Honestly, the MC doesn't even need the other elements. If anything, it's a problem he even tries to directly attack anything, when he can just crush anyone's heart from afar, or paralyze them and have his harem bash them afterwards. The issue is that the MC does not trivialize every single mob he encounters, since everyone should practically be 100 levels below him.
