The spells consume a ridiculous amount of mana, but their power is guaranteed. As I received a passing mark from Armstrong-doushi a few days ago, it can now be used in actual combat.
Maa, personally I usually prefer finishing things off by using long-range magic without having to get up close and personal.
Or rather, I don’t want to encounter an enemy that I can’t fight without having to use the spells taught by Armstrong-doushi.
And, as Luise received the same coaching as me, she also successfully learned four spells: physical enhancement, high speed flight, mobile magic armor and helmet and meditation.
