A Trap?!
Leon thought for a while before shifting his attention to a skill of his that had been collecting dust for a while. His <Spell Weaver> skill had been leveling up very slowly ever since he had gotten it. The main reason for that was because he had never used it to its full potential.
As the name suggested, the Spell Weaver was meant to 'weave' spells. This meant that its true purpose was to create spells from scratch. That said, to be able to make spells from scratch, a mage needed to be able to understand and pick apart mana when necessary. That was why Leon currently thought about using this skill to peer into the mana that made the wall so stupidly durable at this time.
