Thorman used his conjured tower shields to block the whole corridor and Binlow hastily activated a spell from one of his rings to conjure an ice wall one meter (3.3 feet) thick to stop the blast.
Lith could have used the diversion to escape, but charged forward instead. He imbued the Gatekeeper with water magic to conjure a cold aura and himself with earth magic. The combined effects were supposed to protect him from the brunt of the damage.
The fire pillar crushed the shields and melted the ice, yet it still had enough power to turn Binlow's constructs into gas. Nalear gritted her teeth, activating once again the magic shield of her sword while her minions conjured more protections.
Lith struck them from behind with the Gatekeeper, overloading Nalear's sword core and interrupting the Professor's spells. The barrier shattered and the explosion engulfed the four of them, but Lith made sure to stand right behind Nalear.
