The battle William had before with Garlend, and his team was intense, but it didn't start with his full strength. When William met Garlend and fought him, he got more than half of his spirit power consumed by then.
So, he couldn't control his spirit power quite well. But right now, he was able to calmly leave behind part of his spirit power, filled with his lightning spirit element.
And the moment he triggered them, the lightning acted wild, and started to wreak havoc all over Ibra's body. The glaive that Ibra was fond and proud of finally lost its firm grip from his hands, fell on the ground, releasing loud clanging sounds.
As for its owner, Ibra started to twitch as if he got electrified.
William knew the damage and pain Ibra was suffering were much worse than what looked on the surface. After all, Ibra was using a darkness element, something that his lightning element could purify.
