Intercept is a special Interrupt available to an entity that has performed a Block in combat. It is defined as follows:

Trigger

An enemy plays a ranged Action without the Area Attack descriptor that does not include you as a target, and it passes through one or more section borders that you have Blocked.

Effect

You replace one target of the triggering Action with yourself. If you performed the Block at a distance, the attack automatically misses, even if it lacks a Hit entry.
