D&D Nibble: Trailing Ghouls

The great Erol Otus' ghoul.

This is a little thing I’ve been toying with for a while, at least since my old Doom & Tea Parties campaign.  I’m writing it up now because someone on Facebook running 5e was looking for a mechanic to disrupt the PCs taking short and long rests.  That’s never been a big deal for me.  I enjoy this for the horror movie aspect of it.  Either way…

Ghouls are, of course, attracted to dead bodies.  The more dead bodies laying about, the more ghouls you get.

PCs generally leave a LOT of dead bodies in their wake.

The ghoul pack grows the more bodies the PCs leave behind.  Keep track of their kills and add ghouls as follows:

Every 4 Small corpses = 0-1 ghouls.

Every 2 Medium corpses = 0-1 ghouls.

Every Large corpse = 1-2 ghouls.

Every Huge corpse = 1d4 ghouls.

Every Gargantuan corpse = the pack abandons the PCs and just camps out inside the corpse.

 

For every 12 ghouls, add a ghast to the pack.

Whenever the PCs camp for an hour or more, they’ll notice the ghouls at the very edge of their vision, lurking and snuffling about.  Describe the furtive scuffling of their feet, the scrape of claws on stone.  As the pack grows, be sure to let the players know that there are more of them out there.  They grow louder as the pack grows as well.  If the pack comes to outnumber the PCs by at least 3 to 1, they dare to come closer.  They’ll howl at each other, get into fights with one another. 

But they won’t fight the PCs.  Not yet.  They’ll scatter as the PCs approach.  They flee if the PCs attack. 

Until the PCs take an 8 hour or longer rest.

The first time the PCs take a long rest AND the pack outnumbers them by at least 3 to 1, they hungry ghouls will attack about halfway through their rest.  The ghouls will flee when a third of their number have been slain.  And go back to shadowing the PCs. 

The PCs can prevent the pack from growing by disposing of the corpses.  Burying the dead only slows the growth of the pack, cutting additions to the pack in half (rounded down).  Poisoning the corpses does nothing; ghouls are immune to pretty much every poison known. 

Fully destroying the corpses with fire or acid is the only sure way to prevent the pack from growing.  Acid is quicker but both methods are time-consuming, especially if the PCs are trying to use cantrips alone to do the deed.
