The mul & thri-kreen PC races for 5e D&D

Posted on April 28, 2015 by


I’ve been working on 5e monsters and races lately. Earlier this week I posted a Shardmind and a Loxo, and now here are two more races to add to your 5e options (assuming you like them and your DM approves!)

These two races come from the Dark Sun setting, the Mul and Thri-Kreen. The latter is in the game in the form of a monster, but the mul is not. I tried to stay as close to the “feel” of the races as I could. Here’s how:

The Mul, a half human, half dwarf is known for being a tough race. They don’t tire easily, are strong combatants, etc. They are usually found as slaves and gladiators toiling in the harsh world of Athas.  Here’s how I represented that for 5e with racial traits:

  • Tough as Nails. During a short rest you can reroll a Hit Dice roll and take the higher of the two rolls.
  • Resistant. Once a day, if you fail a Constitution saving throw you can choose to succeed instead.
  • Tireless. You only need to sleep 2 hours a night to gain the benefits of a long rest.
  • Mul Weapon Training. You have proficiency with the spear, whip, pike, handaxe and unarmed strikes.

I think I got the feel of the mul down. The re-roll hit dice thing to me is the highlight of the race.

The thri-kreen is an insectoid creature with six claws, also from the world of Athas. I found this one a bit more challenging to translate to a workable race, and it went through various versions. The thri-kreen has a lot of neat things it can do, and there’s a chance of making them a bit too overpowered when compared to other races. They can jump to great heights and lengths, they have psionics, they blend in with their surroundings. Lots of neat tricks, but it can get out of hand.

I think I finally cracked that nut after seeing how the Elemental Player’s Companion handled the Deep Gnome’s magic, via a feat, and the talons of the Aarakocra, via a simple proficiency.

Here’s what I gave  them:

  • Long Jumper. You do not need to move any number of feet to make a full long or high jump. Additionally, roll a 1d12 when you make a long or high jump. The result is an additional number of feet you can add to the total of your jump.
  •  Claws. You are proficient with your unarmed strikes, which deal 1d4 slashing damage on a hit. (EDIT: they were 1d8 but I changed to get out of the way of the monk)
  • Chameleon. You can change your color to match your surroundings. You have Advantage on Dexterity (Stealth) checks made to hide in this manner.
  • Along with an optional feat (subject to DM approval):
    • Thri-Kreen Psionics


Prerequisite: Thri-Kreen

You have telepathy out to a range of 60 feet. Additionally, you have innate psionic spell-casting ability. This ability allows you to cast mage hand at will, without needing a material component. You can also cast each of the following spells once with this ability: blur, invisibility, and magic weapon. You regain the ability to cast these spells when you finish a long rest. Intelligence is your spell-casting ability for these spells, and you cast them at their lowest possible levels.

I am inclined to say that the race is fairly balanced versus other races. The first few versions were a bit overpowered. The claws did many attacks, it had innate casting without it being an optional feat.  I am happy with how it came out.

I’d love some feedback on these, either here or on twitter (@newbiedm).
