Not shared the vsion with a Dummy Unit? How?

[Nocturne]

Is possible to do that?

 

[Arkan]

There's a trigger for that:
Unit - Grant/Deny shared vision of (Triggering unit) to Player 1 (Red)

You can also remove the vision of dummy units...

Just set its vision (I forgot what its called) to 0 in the object editor.. It is found at the stats category.
