"It seem they will not stop the attack." one of the Paladin said, blocking a Fireball with his shield. While blocking a large ball of fire with a metal shield is not a good idea, the magic imbued into the shield is effective in blocking the attack, with ease.
"As the Hero said, they will continue their attack, and forced us to drop dead from exhaustion." a veteran Holy Knight replied, though he clearly find the entire situation hateful.
"There is nothing we can do about it." a Holy Mage replied, "except for letting Lady Mirna attack the flying Archdemon."
Only the Hero's attacks were guaranteed to kill the A-rank Demons. Anything else would only injure if not avoided by them. The Hero's Holy Slash were faster, stronger, and could easily shred an Archdemon.
However, due to the attack using mana, she could not use it all the time, forcing her to hold back or she would run out of mana, and that would be the end of the Expedition Force.
