'This exercise is just like a math problem. I can either learn by rote all the equations or I can understand the underlying principles of the main formula and derive from it everything I need. So far the first method failed me, time to give the second one a try.'
Lith closed his eyes, ignoring the combo bar in from of him and focusing on his mana core instead. The second spell of his choosing was Jorun Bat, a useless spell that would generate coin shaped icicles.
It was similar enough to the previous one to make it possible for him to at least reuse the first hand seal. Lith drew the symbol in the air slowly, feeling a small amount of mana departing from his core.
Then, he almost stopped his hands, making one small movement at a time and observing how the mana strand reacted. He discarded all the signs that caused it to bloat or collapse, following only those which made it move outwards.
