Since the class was starting Calvin had the courtesy of rising a small part of the ground to create a platform where there was no snow to function as a bench, of course he did the same for the teacher.
Everyone took seat and focused their attention on Aliya, which right now rose two of her left hand's fingers.
"I previously taught you about how to reduce casting time and the way to "boost" the power of a spell, without causing it to become unstable right?".
Seeing her students nodding, she pointed at Calvin and then continued with her explanation.
"The way of a mage is to always look for an advantage over its enemy, preparations are the golden rule, never forget that, taking Calvin's fight for example, earth element does counter lightning element, but it's only to a certain extent".
"An amateur mistake I bet you all have noticed on the young generations of the Jolbaris you have seen or fought so far, is that they tend to depend on long range attacks".
