Paragon Benefit (Lantern)

In addition to the other benefits, your lantern reveals all things as they truly are. The lantern's aura of light increases to a 40-foot emanation. While you're holding your lantern, the GM rolls a secret counteract check against any illusion, morph, or polymorph effects that come within the lantern's aura, but only for the purpose of determining whether you and others can see through it (for instance, if the check succeeds against a polymorph spell, you can see the creature's true form, but you don't end the spell). Use half your level rounded up as the counteract rank and your class DC – 10 as the counteract modifier. On a failed counteract check, the lantern can't attempt to counteract that illusion, morph, or polymorph effect again until midnight. You can choose to leave any effect you discover intact instead of counteracting it.
