[MIB.6361]

Ok, so lets say I take it exactly as it's written. 40 point Small VSE Elemental plus the 145 point Nothingness Lens.

I have an Elemental made of Nothingness. It's a swarm of "something" (Diffuse) that's also ghostly (Insubstantial). So it's virtually unhitable unless you can affect Insubstantial, and then you'll only do 1 or 2 points unless it's a cone or area effect.

As an Insubstantial creature, it can float around silently at move 5.
OR, it can use it's Flight for Move 10, but then it goes from being completely silent to Noisy 5!
