The battle ended faster than Roy expected.
Solmyr, who stayed to cover the retreat of the alliance army, was actually a very powerful hero. Unfortunately, he did not choose any other magic to practice but chose air magic. His signature Chain Lightning spell was useless against Roy.
This was the advantage of source magic. Not only could it bring stronger magic power to the user, but it could also allow the user to obtain higher resistance to the corresponding magic element. Solmyr and Roy both used lightning as their source, so the final competition was whose magic power was higher. Solmyr's magic power was not as good as Roy's, so his lightning could not affect him. On the other hand, Roy's lightning could cause a certain degree of damage to him.
