Jack's Infernal Cleansing Flame stabbed into the shield that protected the Chalice of Blood. He had also activated his Storm Breaker's Overlimit when he teleported. Overlimit multiplied the rune technique's damage output by more than three times.
At the same time, Arlcard's Unrelenting Purgatory slammed into the same shield. The shadows of Arlcard's rune technique fused with the shield before countless black swords started stabbing in and out of the shield.
Damage numbers continued to appear as white flames and dark shadows assailed the shield. The rune diagram on the floor that generated the shield shone brightly as it tried to keep the shield intact.
The shield itself was not in perfect condition. It already lost forty percent of its HP when Jack and Arlcard hit it. The archdemon lord's spells hit a large area. This shield also suffered from the archdemon lord's bombardment before its duration ended.
