Latching on to the water elemental mana was the easiest part. Walker had the knowledge and the strength to do that at any time. The very reason was the seemingly endless water all around them. That meant that there would be a very powerful source of water elemental mana wrapped around whatever Walker wanted it to latch on to until he was done with what he needed to do.
The tough part was that walker had to hold the natural mana between himself and the small amount of earth mana that he had already gathered from Terron and Su's training. Even though there was not much of it to spare, Terron had used some to demonstrate the skills that he wanted Su to strive after.
She had seen the stone skin skill and noted that it made the scales on Terron seemed to be covered in a hardened clay type stone. It would definitely reduce any damage taken while also making it harder to break defenses overall.
