James was shocked by the sudden explosion, and quickly entered speed time. He retreated crazily, then set up a barrier using all his elements, which were Poison, Psychic, Ice, Sound, and Dark.
Darkness, Psychic, and Ice formed the main barriers as they could block both physical and magical attacks. Sound and Poison were more technical, with sound grinding down the attacks nature while poison corroded it.
The final attack only singed a bit of James' hair, but it told him never to underestimate his foe. Without his crazy speed, he would have been blown away. Even if he had a good Constitution, he would likely need some Lunar Dew to come back to life.
The arena itself was warped under the power of the explosion, most of the tiles cracked while the area where Ger Kek formerly stood was molten. Soon, maidbots and critterbots rushed over to tidy the place and up and repair the area for the next fight.
