In the center of this valley, Alex saw a small black rock that was roughly shaped. It was just lying at the bottom of a crater carelessly, but if one observed closely, they would notice that it was drawing the energy of the lightning that struck down and was absorbing it.
The black rock looked fragile yet didn't disintegrate when struck by lightning directly.
Alex's eyes gleamed. That was it, the aura that he felt was coming from that rock!
He activated the skill of his mask and directed it at the rock; details about the black rock quickly popped up.
…
[Lightning essence stone: Absorbing it will make a Mage's element to get stronger or undergo a transformation.]
….
The details were brief, but they gave Alex enough information. This essence stone was just like an elemental fruit!
Alex would be lying if he said he wasn't excited, he wondered how strong his lightning element would be after absorbing this essence stone.
