The final part to learning [Shadowbind] was the strength test.
The whole point of learning the Shadowbind technique was to immobilize one's enemy and unless the created binding chains were not strong enough to immobilize the enemy, then it did not matter whether the shadow was 2 dimensional or 3 dimensional, as it was simply useless.
Hence, Leo began testing the strength of various types of chains, and after a few initial tests, he quickly noticed that the internal mana skeletal structure he formed within each chain directly influenced its overall strength.
The first day of testing yielded mixed results—he managed to create a chain strong enough to lift a weight of approximately 5 kilograms off the surface and while this was a promising start, it was far from sufficient for the system to acknowledge his mastery of the [Shadowbind] technique.
