Oscar vs Sanctified Purge, Arifureta Zero Vol 6

“Commander Lelei, I have an urgent report! The effects of our debuff magic appear to be neutralized!”
“Gah, but we only ever showed that to the heretics once!”
In fact, Oscar had only ever heard about the debuff spell, not seen it, but he was such a skilled synergist that a secondhand account had been enough intel for him to work with.
...
“Divine Crusade,” he said simply, raising his staff.
The entire temple was bathed in a dazzling silver light...and a second later, he said, “Sanctified Purge.” The light expanded outward, covering the entire mountain in a silver aura.
“Oh no! O-kun!” Miledi shouted.
“I’ve already activated my purge-countering artifact. But it’s still this effective at weakening us even with that up.”
“I’ll probably bleed my mana dry if I keep trying to counteract it with restoration magic,” Meiru added.
The weakening effect of Lucifer’s spell was far greater than what Selm had achieved with his replica staff. Part of that was, of course, because the main cathedral itself was an artifact that strengthened those who believed in Ehit and weakened heretics. Even when it had just been partially activated, it had been enough to stymie Naiz’s teleports.
...
“This might have actually been kinda tough if we didn’t have your artifacts!” Miledi shouted, her sky-blue mana surging around her.
Thanks to the evolution magic and debuff-repelling artifacts Oscar had made for everyone, Lucifer’s Sanctified Purge wasn’t wearing them down at all.
“Asura!” Miledi knocked down the Paladins and their spells with one wide-area gravity field.
“Your Sanctified Purge doesn’t seem to be doing much!” Meiru shouted as she circled around to cover Miledi’s back.
