Children of the Wind

The Children of the Wind are bloated, corpse-like monstrosities, with stumps for limbs. They are always accompanied by howling, gale-force winds.

(Unfortunately, I was unable to find an image even vaguely resembling a Child of the Wind.)

In the RPG...

Alone, a Child of the Wind is little threat. However, the Malleus Monstrorum says that they always appear in groups of ten or more, which increases the threat significantly. They are not particularly adept at fighting, with their attack only having a 30% chance to hit, and doing an average of 3 damage. Strangely, this doesn't include damage bonus, so adding that takes it up to an average of 6, which is a bit more threatening. If their limbs are stumps, however, perhaps 3 damage is more apt. They also take half damage from impaling weapons, which also adds to their threat. 

    The Children of the Wind didn't make it into the 7e Malleus Monstrorum.

In a video game...

I think the Children of the Wind could work in a video game, though I'm not entirely sure how their movement works. They ride the wind, but can they fly against it? If not, a simple dodge might be all that is needed to avoid a fight.

In a film...

The description of these creatures sounds sufficiently horrifying, so I can imagine them looking equally so in a film. I'm curious how the source story goes, but unfortunately I can't seem to find an ebook edition anywhere.
