Need a spell for a haunt

[LucyG92]

I'm making a haunt that was caused by a group of hunters being lured out away from safety and then attacked/eaten alive by an evil creature (thinking some kind of fey or a hag, maybe?) - just trying to pick a spell effect for it. Given the nature of the haunt, I thought something involving nausea would be suitable but all I can find is Stinking Cloud. I don't think this quite works as it's a poison effect. Can anyone think of anything off the top of their head?

Cacophonous Call?

Also haunts don't have to strictly mirror spells. If you reflavored and tweaked the spell descriptors, the CR shouldn't change too much if at all.
