Review Detail of Slient in Practicing Basic Sorcery for Billions of Times Made Me Invincible

This is what I feel after reading a few chapters in. There is a spell with a questionable naming sense "dark elf evasion spell" with a subpar explanation on the spell. The author needs to read his work properly and cover all doubts in his/her work. Explain fully and shouldn't assume that we the readers, knows and understand what the author is thinking.
