Laicosts (Mousefolk) for Fifth Edition Dungeons & Dragons

Just yesterday, I created a little mousefolk race called laicosts (pronounced LIE-costs). Well, let me take that back: my six-year-old son, Jack, came up with the idea for the laicosts. His description was simple:

“They’re little mouse people and they’re really cute and they can go really fast and teleport.”

Now, I may have omitted the part about teleportation (although, I do love me some misty step), but the rest of his description remained intact.

And much to my excitement, people seemed to respond very well to the cute, little buggers! So today, I think I’ll flesh them out a little more plus add in a couple more variants. And for those who missed the original post, I’ve included the stat block for the laicost and laicost nest boss, as well.

Laicosts for Fifth Edition Dungeons & Dragons

Don’t assume that laicosts are gentle because they look like adorable mouse people. In fact, laicosts (colloquially called mousefolk) are dangerously fast cutthroats, known to haunt under-patrolled backroads and dimly lit city alleys.

Touched by Magic

While many who study the humanoid races argue about the true origin of laicosts, most agree that there was some degree of magic involved. The biggest school of thought posits that laicosts originate from the elemental plane of air, which is how they get their speed. Yet others believe they were created by the Queen of Air and Darkness in the Feywild which would, of course, explain their wicked ways. However, you’d never know from speaking with a laicost; either they don’t know or they’re not telling.

Organized Criminals

The laicosts are hardly a bunch of petty thieves. Laicost society organizes itself by nests, tight-knit clans of soldiers and their families. Each nest is lead by the fastest member, the laicost nest boss. A region can have as many as three to four laicost nests operating at any given time. The leader of all the nests is called the king/queen. However, this is more of an honorary title than anything, since the kings and queens are pulled from laicost nest bosses that prove their speed and wits, and not through bloodlines.

The kings and queens drive the bosses to increase their reach in their respective regions. That includes, but isn’t limited to, ambushing wagons, raiding farms, and mugging pedestrians in city alleys.

Looking for that rare magic item? Just find a laicost. He can tell you how to find no less than three of them; for a little coin, of course. Thanks to their close ties to other criminal organizations, mousefolk use their black market connections to funnel stolen magical items and precious artifacts.

Lightning Tails

Sometimes, a laicost is born with the raw power of the wind and lightning in its veins. Although these laicosts live relatively short lifespans compared to their brethren, they are greatly respected by all and live quite comfortably. Laicost bosses not only see a lightning tail as a great asset to the entire organization but as a favorable sign granted by the Elder Tempest.

laicost-race

 

New Player Option: Laicosts (Mousefolk)

I had a request from some folks on Instagram about making laicosts a playable race. In fact, I’d agree that mousefolk lend themselves pretty well to playable races. However, they are a little weaker than most PHB races, so be sure to okay it with your DM if you plan to play one.

Laicost Traits

Your laicost has a variety of natural abilities, some of which are believed to have been gifted by the Elder Tempest itself.

Ability Score Increase. Your Dexterity score increases by 2 and your Strength score is reduced by 2.

Age. Laicosts reach adulthood at age 7 and can live up to 50 years.

Alignment. Laicosts are selfish, deceptive beings, so they tend towards evil. However, they’re very organized and have close ties to their nest. Therefore, laicosts have a tendency towards lawful, too.

Size. Laicosts are between 2 and 3 feet tall and weigh between 30 and 40 pounds. Your size is Small.

Speed. Your base walking speed is 60 feet.

Darkvision. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

Hit-and-run. You don’t provoke opportunity attacks when you move out of an enemy’s reach.

Keen Smell. You have advantage on Wisdom (Perception) checks that rely on smell.

Languages. You can speak, read, and write Common and Laicosti.

 

Thanks for reading!

Hopefully, the laicosts can add an element of excitement to your adventures! If not as a playable race, then perhaps as a good low-to-mid level challenge.

If you aren’t already, be sure to follow along with the blog by signing up to the email list.

The next time I touch on the laicosts, it’ll probably be with an adventure.

See you then!
