Last Refuge

Seeing this scene, Lin Li knew he couldn't let Asgor continue to attack by changing its soul. Even if he could persist on with his incredible mental strength, Connoris and the two Undead servants would be in big trouble. Hence, as soon as the dizziness in his head dissipated, he immediately pointed the Helios' Scepter forward, and a burning hot cloud of fire shrouded Asgor's head.

It wasn't that Lin Li didn't want to use the World Sword to kill Asgor, but rather that it was difficult for him to concentrate on casting the World Sword under the impact of Asgor's Mental Blast. In fact, if another mage was in Lin Li's place, he probably would not be able to even cast a small fireball.
