Grey Bobble Headed Territorial Poopers

[magnum.arcanum]

In regard to the Greys;

I think were just suppose to blank these things out, right?  What does engulfing them with blue flames do to them?  Anything?  What if you cooked the bastards while you were blanking them out?

Suggestions?

Just kill them, they want to enslave the human race
