D&D General Favorite Underrated D&D Monsters for Low-Level Encounters

[AlexChenDM]

Hey fellow DMs and players!
I've been running a lot of low-level campaigns lately (levels 1-4) and I've realized I keep reaching for the same handful of monsters — goblins, bandits, wolves, skeletons. They're classics for a reason, but I know there are so many underrated creatures in the Monster Manual (and beyond) that deserve more table time at those early levels.
So here's my question: What are your favorite underrated or overlooked monsters for low-level encounters, and what makes them fun to run?
I'm especially interested in:

• Monsters that create interesting tactical situations (not just "it hits you, you hit it")
• Creatures with unusual abilities that surprise players who think they've seen everything
• Monsters that are great for roleplay encounters as well as combat
• Any reskinning tricks — using a stat block in an unexpected way

For context, this community has had some fantastic monster-related discussions recently. The "The Monsters Know What They're Doing ... Are Unsure on 5e24" thread (3,000+ replies!) has been an incredible deep-dive into monster tactics. And "Favorite Creepy Monster To Run?" had some really creative picks. If you haven't seen those threads, they're well worth a read for inspiration.
I'll start: I'm a big fan of the Darkmantle at low levels. CR 1/2, but that Darkness Aura completely changes the battlefield for a party that relies on sight. Watching a well-organized party suddenly scramble when they can't see each other is priceless. Plus it's a great "what IS that thing?!" moment for new players who expect everything to be a goblin.
Another pick: Needle Blights. They look like bushes, they have a ranged needle attack, and a grove of them turns a simple forest walk into a terrifying ambush. Great for teaching new players about environmental awareness.
What are YOUR picks? Drop your favorite underrated low-level monsters below!

And here I thought it was a thread about how WotC broke 6e. 5.5e. I guess I have some reading to do . . .

A kobold with a wand of Fireballs and armor covered with Continual Flame never gets old.

@AlexChenDM welcome to the site.

I like to use a cockatrice or two. They are limiting enough but can paralyze and petrify you. I might pair them with a couple kobolds and have one in a cage that gets thrown and broke open. I have made it a neutral monster and attacked both the kobolds and the PCs. There can always be a potion to un-petrify a PC, but the new MM has it wear off after 24hours if you do not mind having a player sit around. I have done the cage thing with giant rats as well.

One of my favorite low level monster is the Kobold Skirmisher from 4E. Its incredible simple, however, it allows for quite different tactical play. It does not fully translate into 5e, because 5e has different movement, but I still think its a good example.


The skirmisher has melee and ranged attacks and, kobold typical, a minor action (bonus action) shift 1 (move 5 feet without provoking opportunity attacks.)

The way 4e worked was that you cannot split your movement. So you can move before or after the attack but not both.


However, this kobold had 2 movement actions, this means they can perfectly use hit and run tactics. Come forward from a pillar, shoot at an enemy, and then move far away behind another pillar. And even if caught in melee they can just attack, and then shift away and then move away.


Its 1 simple feature, which make theseskirmisher kobolds annoying.



EDIT: In a similar vein I like the "basic" lurker from 4E, although there I have not one specific example. Although if one has to choose 1 I would go for "Shadowdale Drow Informant".


So for me the most simple lurker feature is that they can become invisible at will (until next turn or they attack). So when the combat start they are not there.

Then they normally also have some form of additional damage if they can surprise enemies (like when attacking with combat advantage or from stealth).


So with these annoying things existing, you never know if not suddenly in an encounter more enemies come up, and they are especially good in attacking the backline.

Kobolds because they are small and can thus live in tunnels too small for medium-sized PCs to stand up, because you can come up with all sorts of devious traps. You can mix them up with dangerous trained animals or larger monsters.

Hobgoblins because of their militaristic nature. So they can apply believable and effective, coordinated tactics and have various fortifications for the PCs to navigate. And if the PCs retreat after an incursion, you can bet the hobgoblins are prepared if PCs return.

Both are intelligent and capable of speech, and probably have some purpose or goal besides just being there for the PCs to attack. They could be potential allies for the PCs against other threats, or simply information sources, or they might have prisoners or slaves for the PCs to rescue.
