Booming Voice
Q: Mas Amedda's Booming Voice says it gives "unlimited range" to commander effects. Does that mean
it applies to all eligible allies?
A: No. "Unlimited range" means there is no specific range limit, but you still must be able to count range
to that ally for the commander effect to apply. For example, if the commander is isolated in a room with
all of its doors closed, it is impossible to count range to any character outside that room. Thus,
the commander effect would not apply to any character outside.
OK, so if the commander is locked in a room, a character outside the room can't count range to the commander.
How does the Mouse Droid's Relay Orders affect this? It allows you to count range from the MD,
as well as the commander. Not range 6, as Booming removed that range limit. The mouse does not have to count range to the commander in order for Relay Orders to work. Relay is a special ability, just as Booming is. It just works.
I will gladly insert foot in mouth upon anyone citing/linking to an official source/ruling that directly contradicts my interpretation
Side note: the earlier example about interaction with Disruptive has no bearing on this question
