Vandertz glanced down at Katerina with an expression of concern when he noticed her reaction at the mention of becoming a being of pure energy. What was she pondering about? He couldn't tell for sure, but he carefully allowed her to touch the ground again when she gave that nod.
"Yes, a being of pure energy. Many humans studied ways to reach that form, but isn't easy, blasting someone with magic won't work. You need a strong magical source producing those waves, and apparently the defense towers somehow were enough to get you that far."The Crystaloid raised his other hand towards the human and shook his head once more.
"You won't need to do anything, just hold still. This might sting a little."And without explaining what was going to happen next he made a gesture with that hand as if he was pulling something towards him, revealing a strong glowing rope of energy between his hand and Katerina's body. The process took at least two minutes, and the result large sphere of energy floating near his fingers.
"...This was the excess, and instead of tossing it into the air and let it explode I will use it to make this ore useful again."He tossed the ore up before flinging the sphere against it, still resulting in an explosion that made the ground shake, besides producing a strong blinding light for a few seconds. And finally after the "transfer" was done, the now glowing rock fell on the grass.
"Use this material wisely. Once you put it against or near a weapon, it will transfer all the energy it contains."After all of that Vandertz was still feeling dizzy and with a hand pressed against his face.
"You could have warned us about the explosion and the lights...I feel I had been staring at the sun or something."
