"Can you cast some type of blessing on us to combat the corruption of the death-mana?" Eldrian asked.

The adventurers who now all clearly understood the threat all tried to eavesdrop on their conversation quite shamelessly. Eldrian didn't mind if they heard them talk, but he did mind their lack of basic manners. 

Most of the adventurers weren't all that strong, at least compared to the army. There were a few Tier 6 people in the mix and they were the strongest, most of the adventurers were Tier 4 or 5. There wasn't anyone weaker than that as then even a normal skeleton could become a danger. 

Elizabeth pondered his request for a bit. "I don't think what I can do will be of much help. I can cast a spell to ward of evil, but... I don't think death-mana is inherently evil."

"Oh, why do you say that?" Eldrian asked though he agreed with her. Saying it was evil is the same as saying gasses that are harmful to a person are evil, like carbon monoxide (CO).
