When a rogue with this talent hits a creature with a melee attack that deals sneak attack damage, any non-magical light sources worn or carried by the creature (such as lit torches, lanterns, or sunrods) are automatically extinguished. Once per day, the rogue can use this ability to also attempt a dispel check (as per dispel magic) against any magical sources of light a target carries, using her rogue level as the caster level.
