He could not do it, despite all of his efforts, Alan failed to bring the Giant down, the fragment of Kizmal was far, far too powerful for him.
Whatever he tried, the giant would simply shrug it off. Worst of all, he could hardly even do anything... Whatever he had learned was useless.
His very being was electricity itself, even stepping on his body as a human, or climbing it as a dragon was futile, the electricity would paralyze him within moments.
The fragment of Kizmal was a beast, one he had no chance at taking down. He was of the opinion that things were going well, but he was wrong...
The fragment was strong, his skill had a short cooldown of only thirty minutes, thirty minutes... and he was able to use the eviscerating beams of energy again.
And that was not his only skill, he could summon storms with lightning that chased you around, lightning so powerful his scales would be helpless against it.
