Unknowing of the poor trolls suffering abuse, Milo stared at a piece of paper in front of him, looked left, looked right and seeing that everyone was approaching this test with confidence, deemed that the questions he had just read weren't traps.

Perhaps he was just traumatised by Helena's shrewd and inhumane idea of what a test was supposed to be, but the questions were rather straightforward, fitting of their teacher, who always approached every subject like doors that needed to be kicked open.

The first few questions were about mana crystallisation and cores, though that was the name the lesson was called, it also covered other things in relation to them as well.

In this case, crystallisation referred to that of a mage's own mana, rather than the crystals that could be found in the wild, it could occur naturally or by the will of the mana user, the first question pertained to the difference between the two.
