Trust a Flumph.
X the Mystic’s 1st Rule of Dungeon Survival
I want to know how this monster came to exist. Was someone on the staff super drunk and/or stoned? Or did they just put a paper and crayons in front of their kids and say “Draw me a new monster or daddy can’t pay for food this month.”
Either way, I’m mildly grateful. But only milldly.
Lore: The Only Parasite That’ll Betray Their Host
While a Flumph resembles a floating, glowing jellyfish, they’re actually highly intelligent, possessing knowledge of ancient religion, philosophy, mathematics, and other such subjects. Their psychic abilities make them keen to the emotions of others. While they are drawn to positivity, they flee from evil.
They feed off of mental energy. Their often found feeding off of monsters like mind flayers, aboleths, githyanki, and githzerai. As passive parasites, they’re often unnoticed by those they feed on. However, the good nature flumphs are often frightened by the negative thoughts they consume. Thus, when a positive source of food appears, they’ll share the information in hopes of getting assistance in destroying them, even if it means finding a new source to feed on.
Flumphs live in cloisters with each other. They won’t designate their leader. Each one contributes in their own way and communicates harmoniously, making it easy to make do without one.
The lore here is pretty fun! You can very easily write a compelling questline with this. Maybe the party could stumble into a cloister while struggling against some kind of threat. Or perhaps the Flumph could seek them out for help, marking the beginning of this quest. Hell, you could do the opposite if you’re running an evil campaign!
Which is where you’re really gonna get utility out of this thing, let’s be real.
Design: Why’d You Give a Jellyfish Eyes? And a Mouth? Is that a mouth? I think it’s a mouth. We’ll call it a mouth.

I’m honestly not sure what to think about this design. Like… it’s certainly unique. A floating jellyfish with eyeballs? Yeah, that’s certainly something new.
But it doesn’t do a whole lot for me in terms of a story. Tell me: what part of this says “psychic parasite” to you? It looks like a filler monster you’d find in a seaside setting. Not something you’d find in the Underdark.
Like… maybe if it were a floating brain or something like that. But a jellyfish? I don’t really get it. That’s not even a parasitic creature!
At least, I don’t think it is. Hold on… *goes to Google* No, I’m right. Kind of.
Stats: If You’re Fighting One of These, You’re a Bad Man
Wow. Challenge level 1/8. I think that’s a new one!
This thing is basically a joke. Sure, you can’t read its mind. But when it literally has to make a save to avoid being incapacitated when they’re knocked prone? You’re dealing with a gag.
Also, if you hit it with psychic? You win. Its HP is so low that you won’t even need to roll.
Its attacks are slightly more threatening. Its damage isn’t super menacing, but the extra potential acid damage can help. Unfortunately, the DC is so low that the player would more than likely succeed.
But what about its unique attack, Stench Spray? Well… it can poison the victim. And… yeah, that’s it. Helpful for a quick getaway! Not so much for a compelling fight.
Which, again: you’re really not meant to fight this thing. Unless you’re a bad man.
Placement
The flumph is a monster that gets less fun the further down the page you get. It has a fun name and decent lore! And its design, while not very effective, is certainly unique. But you can’t really make a fun combat encounter out of it.
With all that in mind, let’s put the Flumph on the Best of the Bestiary!

Yeah, from the (original) Fiend Folio onwards… (A)D&D monsters got, let’s just say interesting. You could see where, sometimes, they were desperate for something! Anything!
Yeah, I’m old. I remember when the original Fiend Folio hit the shelves. Not that we could buy it off the shelves… In our small Bible-belt city, it was almost all mail order back in those days! The one store that carried RPG stuff stocked up basically once a year. Well, George did that for everything… He was an interesting character.

Dude, I love the old Fiend Folio. It’s got a charm to it. Even if some of those monsters were really dumb.
