Vale doesn't have a decent counter-spell against the undead minions of the Necromancers.
Most of his Dark Spells were better used against living beings. As a matter of fact, he also had three Necromancer Spells with him, and they were all useless against these zombies and skeletons...
In the end, Vale chose to end this quickly by using one of his Celestial Arts.
Vale briefly focused as he activated one of his Spell Lights. As soon as he felt the deduction of his Divinity Points, the sky above them suddenly changed…
"Don't follow me!" Vale shouted as he unleashed the Divine Lightning.
Boom!
In an instant, a bolt of lightning streaked through the sky, illuminating the dark battlefield.
The crackling energy struck with precision, obliterating all the summoned undead creatures at the same time.
