Jack looked at his minions that were all inside this lightning prison, Therras, Spirit Weapon, and Peniel.
Therras had very high HP and also high defense due to its armor. With its current Sovereign Mode, which was what Peniel called it when it transformed under his Ultimate Beast's effect, it should be able to tank through the spell. If it got too dangerous, he should still be able to unsummon it in time.
Peniel was small and fast. But Jack had seen the speed of this Perpetual Lightning Judgement. It was not something that could be dodged. Not to mention the sheer number of produced lightning was unreal. She had an innate reduced damage ability. If her HP dropped too low, she would go into an automatic invincibility state. However, he was not sure if Peniel would not be one-shot by the lightning.
The spirit weapon was like Peniel, fast and had a slim frame that made it difficult to be hit. But its HP and defense were not that impressive.
