Exploding Divine Lightning

After walking for about five minutes, they stopped in front of one of the trees in the forest. This particular tree has a width enough for five adults to wrap their arms around it. 

"I will go first," Lawrend said.

He stood 10 meters away and took a stance before pointing his finger towards the trunk.

"+Shock Arc+!"

Zap! Boom!

An arc of golden lightning escaped his finger and hit the trunk. It zapped the tree and made it glow golden. While a small chunk of its trunk exploded outwards in a small explosion.

With the trunk's size that damage was insignificant to it.

"What? Is that it?"

Lawrend stared at it in disappointment. It wasn't any different than his purple lightning before.

"Wait, Master. Look, it's still glowing golden," Aezel said.

Lawrend looked at the trunk again.
