Decumia didn't counter the Foolery's offensive. She didn't stop the mindless charge or the intense hunger. Her approach carried power and secrets that Wilfred and the pig didn't completely understand.
Of course, the Foolery didn't care about the event or the details behind it. The pig glanced at the shallow cuts on its body before lowering its head in preparation for its next charge.
Instead, Wilfred had a more careful approach. He needed to be the mind of that team, but he felt pretty lost when he reviewed what had just happened.
Decumia didn't do anything special. She had detonated her technique to generate energy that could hurt the Foolery. The severing of any connection with the explosions was the only unique aspect of the attack.
