Father Spec looks at the torch, and the right side of his mouth begins to curl up in spite of himself. He *loves* these moments.
"Genetheto phos" he says, snapping his fingers. As he does so his thumb begins to glow brightly, illuminating a 20' radius brightly. It looks like the thumb is glowing white hot -- the illumination extends even another twenty feet beyond that -- and it overpowers the effects of the torch. He holds his thumb up, and proudly states, "I can see fine without it..." before chortling to himself.
The reaction of his compatriots suggests they are surprised, so he holds his thumb up to his lips and blows it out, dismissing the effects of the cantrip. His thumb returns to normal. He shakes it out, pretending he has suffered a light burn.
"My apologies," he says, immensely proud of himself and not clearly sorry for anything. "But I have my own light, and you can save your torch." Saying that he casts the spell again on the head of his mace, and lifts it up to illuminate the corridor.
