DnD 5E Rat Monsters

Hello zoologists of all shapes and sizes! Welcome to my spellbook and thank you so much for checking out the 24th episode of our beast series. Today we’re taking a look at what is the rat monster? which is one of the more interesting familiars and also provides a very good kind of subtle hint as to things to come, i’ll talk about that a little bit later on as well.

So the rat is considered to be cr0 that is to say it’s not really meant to be much of a challenge, at least in its current iteration and it is found in the basic rule set, it’s fun in a variety of different books from the dmg, phb, just kind all over the place. Now without further ado let’s take a look at its actual stats here.

DnD 5E Rat Monsters Stats

  • Type: Tiny beast, unaligned
  • Armor Class: 10
  • Hit Points: 1 (1d4 – 1)
  • Speed: 20 ft.

The rat is considered to be a tiny beast and that is unaligned. It has an AC of 10 and one hit point calculated by rolling a d4 and subtracting one. It also has a movement speed of about 20 feet which is actually relatively low, i thought it’d be a lot of higher but i guess not. Now taking a look at his stats here. Do you know that is there a playable rat race in dnd?.


  • STR: 2 (-4)
  • DEX: 11 (+0)
  • CON: 9 (-1)
  • INT: 2 (-4)
  • WIS: 10 (+0)
  • CHA: 4 (-3)
  • Senses: Darkvision 30 ft., Passive Perception 10
  • Languages:
  • Challenge: 0 (10 XP)

You’ll see he’s certainly not strong, certainly not smart and certainly not charismatic. Outside of that he’s not really good at anything. Now taking a look at his senses he has darkvision up to 30 feet which is okay and it has a passive perception of 10 which is certainly isn’t the worst we’ve seen so far. Have you seen our dnd rat king.

Keen Smell: The rat has advantage on Wisdom (Perception) checks that rely on smell.

He also has access to keen smell which grants him advantage of perception checks related to smell which is pretty cool! Now a lot of you are gonna notice there’s no stealth modifier here which i consider to be pretty disappointing but whatever it’s just the way it’s written. Now let’s take a look at his actions here. Do you know how big are giant rats in d&d?.


Bite: Melee Weapon Attack: +0 to hit, reach 5 ft., one target. Hit: 1 piercing damage.

He can take one action and that is a melee weapon attack referred to his bite. It is just a straight d20 role to determine whether or not it’s a hit or miss. Reach of five feet because it’s meelee. It can only target one target and deals one piercing damage. Now i would use the rat is a precursor of things to come.

For example a rat could be a great indicator of zombies but if you want to get even more creative a rat could be evidence of other rats. For example the cranium rat 5e or the diseased rat or the various swarms in there of. I’m sure there’s a couple other different variants but those are the first two that come to mind. So it could be an interesting kind of indicator.


That being said, how would you fold the rat into your games. Let me know down beneath in the comment section, i really do appreciate it. Also be sure to mention if you have any thoughts, questions, comments or concerns. That being said, i hope you all have a great day and as always happy researching.
