Quote:From the Telepathy description

You may also be able to glean thoughts from an opponent with lower TEC, though this requires time, concentration and skill. When not in a battle situation, for example, and with a TEC much higher than your opponent's, you could probably pretty easily tell what a person is currently thinking. Reading deeper into someone's thoughts without their permission would require at least double their TEC. Particularly guarded thoughts or history would be like trying to open a security vault; it's unlikely that you would be able to get in unless the person was asleep or otherwise preoccupied, so that you could focus on reading their mind without them noticing. If someone wants you to read their mind, or is free and open with their thoughts, you can essentially disregard their TEC.
