When Shingi's attack was a success over the mana sphere, Jathurth stopped his attacks and fell to his knees. Shingi didn't detect any change in Jathurth's HP aura, but there was only one way to test if anything had changed.
He ordered his one offensive Golem that had survived fighting Jathurth to make an attack. Jathurth didn't react, as it seemed like he was in a temporary stun state. As the Golem turned its hand on a blade and its attack made an impact, Shingi noticed that Jathurth's HP was finally affected.
"Everyone attack with everything you have." [Shingi]
Shingi quickly used Mana Seeds to cast HASTE to the Rogue Trio, Wild Tycoon, and An. He wanted to increase everyone's attack range; typically, five was over his limit without boosting his INT. Still, he wasn't going to hold the Spell for long.
