Mc is, yet again, wholly passive for yet another chapter or 2.
Not figuring out how to summon elixirs without paper, or taking out ones from back when he could and he (obviously, as anything else is stupid) summoned a whole stockpile of them to hide.
Not summoning more summons to overwhelm the oders.
Not summoning any summons for defense.
Not summoning any summons to overwhelm enemy guy.
Not summoning any spatial-element summons to lock enemy down so he can't flee.
And so on. all he ever does is attack the pillars.
