Tactics
They are not frontal assault units and do not throw their lives away. Using stealth, or a single scout with Invisibility (scroll) they shadow a party for a while, a day or even days. Using local intermediaries where possible, they set up an ambush. Or at least a favorable position with high ground and cover. They use gaseous form to get into an unexpected position and take on a hero group one by one. They pepper the group at a range, using superior movement to displace when pursuers get too close, then circle back around once all opponents are catatonic. They are a slippery opponent and if the party loses their cool, they will find themselves out of position.
