Note: This is not my trick. The build in which it was used was created by the Vorpal Tribble for Iron Chef XI: Blade Bravo. Excerpt from the Vorpal Tribble's build:
"First off I want to introduce you to my favorite part of this build. It is without a doubt overpowered. You might even say cheese. The Xorvintaal Exarch template grants you telepathy 100 miles to speak with your patron dragon. The Mindsight feat allows you to determine the square of any and every creature with an Int of 1 or more, their Intelligence score, and their creature type within range of your telepathy ability. As such... Wruk now knows every single creature within 100 miles. I just gotta say it again. 100 miles up, down, and around. 'Nothing' can hide from him. He knows how they move, where they are going, who is meeting who... and with his Autohypnosis check he can memorize it. He can keep track of them all, though he'd probably ignore most of the population unless looking for gatherings of specific folks of certain mentalities and types, but those of unusual creature type or those with high intelligences he'd keep in his head. Also, anyone he'd meet he'd note their int, type, and follow them mentally. In fact, it'd be unlikely he could become lost because he'd have the entire layout of a city by seeing everyone passing through and around. It'd be like thousands of points of light flowing in and around a 3-D lay-out. I know if a gang is following me by their collective scores I met before, and can avoid them. I can't be caught flat-footed because I know where they are behind me. "
