Six Tomoe Singing Lightning

The Six Tomoe Singing Lightning is a trap-seal developed by Uzumaki Anjin in his own work with the Six Tomoe Sealing Style. It can be placed on the user's hand and transferred on contact, or placed on a surface and rigged to activate from some sort of trigger. The seal itself releases a ironically silent burst of lightning chakra that electrocutes anything with a chakra signature within several meters, usually fatal to most shinobi below elite Jonin.
