The Mirror Cloak on the Grim Reaper had caused Allen enormous trouble in the battle just now.
Spells like the ones Allen had cast moments ago—the lightning powerful enough to be seen from the distant Great Wall, and the colossal beast formed by Protego Diabolica—had all seemed powerless before this mighty piece of equipment the Grim Reaper had made himself.
