Slaadi: Evil Frogs From Limbo

Five whole pages in one article? Oh boy. This is gonna be exhausting.

Lore: Toads of Chaos

Within the Ever-Changing Chaos of Limbo, a realm every bit as bizarre and untamed as the name might suggest, the slaadi exist without law or discipline. They follow only one rule: might makes right. Should a slaadi prove too weak, they’ll either find themselves enslaved to a mightier foe or simply killed.

Primus, overlord of the modrons, created a massive and complex stone imbued with the power of law, which he cast into Limbo with the aim of bringing order to the madness. Indeed, as its power grew, it did just that, allowing more intelligent Limbo dwellers to create safe havens. However, the item wasn’t without negative effects; the chaos energy it absorbed gave birth to the slaadi, who went on to wipe out every enclave within Limbo. Alas, Primus deemed them beneath his notice and allows them to run free.

The reproductive cycle of the slaadi is nothing short of horrific. Either they implant a humanoid host with an egg, ala Alien, or they transform them with the chaos phage disease. Each color of slaadi transforms in different ways, retaining its memories with each new form.

Red slaadi implant eggs in their victims via glands beneath their claws, birthing a tadpole that eats through its host until it reaches full size. Blue slaadi inflict terrible transforming diseases via hooks protruding through their hands. The highly intelligent green slaadi uses magic. Gray slaadi are the errand runners of the death slaadi, doing work in the Material Plane; they transform once they eat the full corpse of a death slaad. Finally, the death slaadi themselves are evil and chaos incarnate, forcing their lessers into wars against the other Planes.

Slaadi that emerge from the Spawning Stone have a fragment of the stone imbedded in their brain. Powerful magic can draw the stone and use it to enslave the slaad. Should the stone be destroyed, the slaad is set free. Those born in other methods don’t have the stone, but gain one should they come into contact with the Spawning Stone. Which is quite likely, as they are naturally drawn to it.

There is a lot you could do with this lore. I should know; I had a DM who used these guys for a campaign, and every encounter with them was a nightmare! Perhaps the players need to fight their way up a slaadi hierarchy as they invade, with a death slaad as the BBEG. Or perhaps they run into a slaad being controled by a powerful wizard and need to stop them before they open the door to more slaadi. You could do something with Limbo and Primus. There are tons of possibilities, all of them really cool!

Design: A Rainbow of Murder

Five monsters. Five designs. And somehow, all five of them are fantastic!

Each of these designs fits the corresponding slaadi perfectly. The red is thinner, with massive claws, while the blue is much bulkier and stronger. Meanwhile, the green is a hunch-backed wizard, the gray is like a deadly assassin, and the black is a massive, intimidating amalgamation of all the others.

Plus, they’re just plain intimidating! I wouldn’t want to be on the same side of the same planet as any of these guys!

These designs are rock solid. Each one is unique, interesting, and intimidating, perfectly fitting the monsters they’re attached to. Who’d have thought that giant murder toads could be so cool?

Stats: Colors and Death

Embedded in a Slaad’s brain is a magic gem. Acquire it, and the slaad is yours to command.

Six stat pools to get through. Each of them, save for one, taking up nearly half of a page to themselves. Hoo boy. This is gonna be a big one.

First, let’s look at what they have in common. Each slaad has resistance to acid, cold, fire, lightning, and thunder damage. On top of that, they each have the Magic Resistance and Regeneration abilities (except the tadpole; they can’t regenerate). All of this makes these guys a caster’s worst nightmare.

Slaad tadpoles are the weakest of the lot by far. Their AC is low and their HP is low enough that even a level one wizard could kill it in one hit. It’s only attack is its Bite, which doesn’t do much damage at all. Plus, it’s literally tiny, so you could stomp it to death if you wanted.

Red and Blue slaadi are almost exactly the same. Blue slaadi have higher AC and HP, as well as higher damage. But they share the same Bite and Claw attacks as the reds. Difference is in the claws. Red slaadi claws can implant an egg in the victim, which can grow within the host, weaken them, and eventually kill them. Meanwhile, the blue’s claws leave the chaos phage disease, which renders the victim unable to be healed and reduces their maximum HP by a hefty chunk every 24 hours.

I hope I don’t need to explain why either or is a nightmare to deal with.

Green slaadi are powerful spellcasters. On top of having the Shapechanger ability, they also have a staff and can hurl flames as an action. Now, let’s look at their spell list.

  • At will: detect magic, detect thoughts, mage hand
  • 2/day each: fear, invisibility (self only)
  • 1/day: fireball

Gray slaadi are much the same, except they’ve replaced the staff with a greatsword (that is weaker, somehow?) and a different list of spells.

  • At will: detect magic, detect thoughts, invisibility (self only), mage hand, major image
  • 2/day each: fear, fly, fireball, tongues
  • 1/day: plane shift (self only)

Finally, we have the strongest one of them all: the death slaad. Which is just the gray slaad, but it has the Magic Weapons ability and some new spells. These are:

  • At will: detect magic, detect thoughts, invisibility (self only), mage hand, major image
  • 2/day each: fear, fireball, fly, tongues
  • 1/day each: cloudkill, plane shift

All of this can make for some interesting and tense encounters. One hit is more than enough to put any player in mortal peril. If you want to make the players shit themselves, these are the monsters for you!


This is a surprisingly strong entry! The lore, the design, the stats, it all works! We’ve got a top twenty contender on our hands here!
