Jason suddenly modified his thunder bird by making use of the green thunder. Long tentacles made from thunder shot out of the bird and wrapped around Agatha.
The water mage was using a shield of water to protect herself and majority of the damage was absorbed by that shield.
Unfortunately for her, Jason sent a second shock wave through, one made from blue thunder. The tiny impulses went unnoticed by Agatha and directly hit her body.
The blue thunder instantly spread throughout her body and made her lose control over the sea serpent for a few seconds.
Jason made his thunder bird charge forward. Only the divine thunder was left behind and Jason made sure to use its full power to destroy the sea serpent.
This resulted in another explosion that gave him the perfect cover to prepare another attack. However, Jason didn't make any moves and simply remained on his spot.
