I Win

Allen sensed Essence moving through the ground underneath him. When he sensed the correct location, he jumped high into the air, his Essence Soul turning around. 

Alena appeared in a pool of magma where her brother had been and was not surprised to see him no longer there. No one would wait for her to attack them, so she had already guessed that he would fly into the air.

She looked up just in time to see the Ice Essence Soul turn around with his back full of spikes pointed at her. Then, it shot out the spikes.

Like bullets from a machine gun, the ice spikes all fell to where the princess was. The princess immediately reached out with the tendrils of her own Essence Soul, forming a sort of net above her that took the brunt of the entire force.

She felt a slight pain in her body because the Essence Soul took some damage, but it wasn't something she could handle. The net disappeared and a javelin appeared in the Essence Soul's hand that dripped with magma.
