Two seals connected by a(n invisible) tripwire. When the tripwire is triggered, both seals immediately activate. Exploding tags are the standard application, but the technique is not limited to them. The ‘tripwire’ is pure chakra.
Additional Rules and Clarifications Edit
- A Lesser Barrier Formation seal can activate any other seal regardless of what kind or whom it was made by.
- LBF can have zero or one seals attached to each end. Attaching more than one seal to an end will result in Undefined Behavior which will probably be user-hostile.
