I don't feel like reading this anymore ever since he started teaching his skills to other people ╮( ̄▽ ̄)╭ it made him not unique/ special ( ̄∇ ̄") and lost the impact of the story so far ┑( ̄Д  ̄)┍

What, have you not caught on? How many RPGs have you played in your life? Surely you know what Party means? That's what we're seeing the makings of.
Mana Arrow, Flight, etc, you realize these are all existing spells, right? Not unique to him? Other people can and do use those same spells? What makes him 'unique' is how his gamer skill instantly teaches those abilities, and now we know he can apply those to party members. That's super OP; so long as he can trust them, he could power-level a personal army with anyone.
She does not seem to have Inventory, Gamer's Mind, Create Party, or any other gamer-only skill while independent of his party. She was simply able to bypass years of training and reading magic books through the application of his unique Party skill combined with his Skill Book and Stat Allocation abilities. She is not a Gamer like him, she's just someone whose been boosted by it.
