Mergoblins | Monsters for Dungeons & Dragons Fifth Edition

Killing time ’til my Saturday campaign, I thought I might try out something a little different here.

If you haven’t noticed yet, I love goblins. In fact, of all the humanoid races I’ve created variants for, I’ve made more goblins than anything else. Something about them that I think is just so classic and cool. Heck, even one of my NPC “heroes” is a neutral evil goblin named Jeth.

Anyways, with this mini-series, I had an idea: what if I took a goblin, then randomly selected a monster out of the Monster Manual to combine it with. No matter what I landed on, I’d have to turn it into a monster.

For this first go-round, I landed on merfolk. Hence: mergoblins, goblins of the sea.

What is a Mergoblin?

Like land goblins, mergoblins lurk in dark places such as trenches, the remains of sunken pirate ships, or dense coral reefs. They’re just as skitterish as their air-breathing cousins and don’t take kindly to strangers; especially if those strangers are mammals!

Mergoblins tend to travel in schools, so if you come across one mergoblin there is probably a few more nearby.

Like I said, I love goblins. So you can definitely expect me to cook up a few more.

See you then!
