Friends and Foes of the Multiverse – Planar Monsters

Planescape map by monorok

“Across countless planes and dimensions lie incredible creatures.  Such beings may be as mundane as one’s neighbor or far too alien to fully comprehend, perhaps even somewhere in between.  Different realities hold different possibilities… including different possibilities for existence as a whole.  I, your humble xenonaught, shall explore and chronicle the vast reaches of this known realm and beyond!” – Garvin Gorb, Fire-Blooded Genasi Sorcerer, Planar Researcher for the Great Library of Sigil

Throughout the D&D multiverse, there are a plethora of powerful monsters and strange foes.  In some instances, their desires and goals can be met easily, gaining a trusted ally in an alien realm.  Many wield powers never before seen by a denizen of the prime material plane, while others seem like familiar variants of the all too familiar.  Here is a list of a few examples of fantastical planar monsters and NPCs encountered on various worlds, planes and the like.

Author’s Note:  So, I’m getting back into the swing of things, slowly but surely.  Or at least, as best as I can during retail holiday season, as day jobs help pay the bills.  Anyway, I kinda dropped my horror content out of the blue.  Usually, I keep that ball rolling well into December, but I kind of dropped it this year.  Likewise, my patreon needs more updates than what I’ve been giving.  Anyway, I’ve been finding either older books or reprints on DM’s Guild lately and it has made me quite nostalgic.  While I can’t recapture those days with older editions, I figure I can transport some of my favorite things to the current edition.  I hope everyone enjoys this as much as I do.




Swarm of Cranium Rats Variant: Psyker Swarm

The swarm gains the following:

Mind Blast (Recharge 5 – 6).  Ranged Spell Attack: +5 to hit, range 60ft./120ft., one target.  Hit: 11 (2d10) psychic damage.  Hit targets must also make a DC 13 Constitution saving throw or be incapacitated and have speed reduced to 0ft. until the end of their next turn.

  • Author’s Note: You gotta have the Mind Blast!  It’s one of the reasons why I don’t really like the VGtM version, myself.  One big spell goes off and then it’s stomping time from the party… Where’s the fun in that?

Cranium rats are said to be especially deadly in numbers.  This is especially true when the numbers swell to large proportions.  The chattering masses can unleash powerful psychic magic upon all sorts of foes, unleashing destruction wherever they go!  Some say that whatever hivemind that controls them becomes stronger with such high numbers.

Innate Spellcasting (Psionics). The swarm’s innate spellcasting ability is Intelligence (spell save DC 15). As long as it has more than half of its hit points, it can innately cast the following spells, requiring no components::

  • At will: command, comprehend languages, detect thoughts, magic missile
  • 3/day: confusion, hold monster, synaptic static
  • 1/day each: dominate monster, telepathy

  • Author’s Note: I wasn’t really happy with the Volo’s Guide take on them.  So, here’s a big cluster of them proving that Cranium Rats should be a force to be reckoned with in high numbers!




Tall and somewhat humanoid, this blue being wears flowing robes which compliment its eccentric movements.  It is wearing many expensive garments and fine gems.  Despite looking so tall and wealthy, they prefer to avoid direct conflict and are rarely adept to combat.  As such, they’re often seen around various bodyguards.
