Nimble 5e Boxed Set (Deep Dive & Review)

Over the past few years, we’ve seen the emergence of a number of tabletop RPGs built using the core rules of Dungeons & Dragons fifth edition (which is free to use by publishers and fans under a creative commons license). These 5E-adjacent titles range from major releases like Kobold Press’ Tales of the Valiant and ENPublishing’s Level Up Advanced 5th Edition, to dozens of smaller titles borrowing either all or part of 5E’s core mechanics.

Few, however, have dramatically reimagined what the game can be as much as Nimble. The brain child of designer Evan Díaz, Nimble is an aggressively streamlined version of D&D 5e that’s designed to be both fully compatible while also addressing many of the system’s long-standing flaws. The game was Kickstarted back in late 2024, but you can pick up the boxed set now from your local game store or the Nimble website.

So does Nimble deliver on its promise of a faster, cleaner 5E? Below, we offer our take and dig into all the details. (NOTE: For full transparency, I have NOT received any review copies from the publisher and purchased the Nimble 5e boxed set from my local gamestore with my own funds).

What is Nimble 5e?

Nimble 5e is a standalone fantasy tabletop RPG created by designer Evan Díaz. The game initially began as a zine meant to capture popular house rules for D&D 5th Edition, but quickly grew in size as Díaz began to realize he had the basis for a much larger and more complete system.

Eventually, a first edition of Nimble was launched and fully funded on Kickstarter in late 2023, consisting of a single core rulebook. In 2024, Díaz launched a Backerkit campaign for a Nimble second edition that expanded the materials into three rule books, along with more professional-calibre art and a variety of accessories. This new version of Nimble 5e was later released to the public in late 2025.

Mechanically, Nimble is meant to be a faster, more tactical, rules light version of D&D 5e. The game’s biggest shift is the inclusion of a three-action economy (replacing 5E’s patchwork of actions, bonus actions and reactions). Every meaningful decision (moving, attacking, casting etc.) costs an action, with disadvantages on multiple attacks.

Another major component of the game is that there are no rolls to hit, instead you only roll damage dice (with a 1 being a miss and max damage being a critical hit that lets you roll an additional damage dice). What’s more Armor reduces incoming damage, rather than providing a base Armor Class that determines how difficult you are to hit.

Other major features in Nimble include condensing the six D&D ability scores to four core attributes (Strength, Dexterity, Intelligence, Will) and replacing spell slots with a mana point system with no learned/known spells and the ability to upcast more powerful spells by using more points.

What’s in the Nimble 5e Boxed Set?

The current second edition of Nimble consists of three paperback-sized hardcover books, all of which are needed to play the game:

• Core Rules: A 60-page guide containing all of the base rules.
• Heroes Book: An 80-page reference with all 12 character classes.
• Gamemaster’s Guide: 114-pages of GM rules and tools, along with 3 adventures.

Notably, you can purchase each of these books separately but all are included in the Nimble boxed set, which also contains:

• A black slip-box with gold foil
• An additinal one-shot adventure (Meat for the Crab King)
• A cloth map of the starter region
• A five-panel GM screen
• Tarot-sized monster cards
• Action cards, spell cards and item cards

It’s worth noting that the production quality with the Nimble 5e boxed set is exceptional, with the books featuring glossy, high-quality paper, solid binding and some absolutely gorgeous artwork that’s easily on par with anything being produced by even large publishers like Wizards of the Coast.

What’s the gameplay like in Nimble 5e?

A smarter 5E action economy

Nimble drops D&D 5e’s sometimes-clunky mix of actions, bonus actions and reactions. Instead, every character gets three actions per turn, and every meaningful choice costs one or more of them. To counter multi-attack abuse, additional attacks carry cumulative disadvantage, pushing players toward creative choice rather than simply spamming attacks. The result is a 5E-based action economy that’s faster and offers far more player choice.

The game also includes three cooperative actions that players can use to support one another, including Interpose (essentially one PC can take the place of another), Help (providing advantage to another player) and Assess (learning about an opponent or situation and sharing this knowledge with another player). It’s another layer that provides even more meaningful and cooperative play to 5E.

A faster and more tactical version of 5E combat

Nimble’s approach to combat also solves a number of major 5E friction points. The most dramatic change is that you don’t roll to attack. Instead, you roll only damage dice, although if you roll a 1 you automatically miss. The game also includes what it refers to as “exploding crits.” This occurs if you roll the maximum on your damage dice, which allows you to roll another damage dice. If you get a crit on that one, you get to keep rolling, potentially leading to massive amounts of damage. It’s a fun and flavorful mechanic that’s far more satisfying than a simple nat 20.

There are also a number of minor but meaningful tweaks to combat, including Initiative order determined by the player who started the scene and then going around the table. Players then roll Initiative to see how many actions they can perform, with the Surprise condition eliminating actions. In addition, dying characters remain active (using one action per turn instead of making death saves) while Conditions are condensed and streamlined, further speeding up combat.

Armor and damage that actually makes sense

Rather than providing a base AC which determines how difficult your character is to hit, armor in Nimble reduces damage when the defender chooses to use a Defense reaction (costing 1 action). Light, medium and heavy armor affect how much damage is mitigated, while unarmored characters rely on Dexterity.

This solves multiple 5E issues: Heavy plate armor no longer makes you “harder to hit,” just harder to hurt. In addition, it means more hits actually land in battle, which is far more satisfying than the roll and miss which often happens in a typical D&D 5e battle. It also creates more consistent pacing and a system where weapon and spell choices matter.

Streamlined stats and skills

Nimble also trims the six D&D 5e abilities down to just four core stats: Strength, Dexterity, Intelligence and Will. While purists might balk at this prospect, the result is a far more streamlined approach to attributes that removes some of the clutter from Charisma and Constitution (the latter of which is particularly less impactful given how hit points, Armor and damage now works in Nimble).

The game also includes just 10 skills (as opposed to the 18 featured in D&D 5e), which again makes for faster and more streamlined play and is also much easier to learn for new players. One minor quibble is that the names have changed, so it may take you a bit of time to figure out the differences between the standard 5E skills and the ones presented in Nimble.

Spellcasting without the fluff

Nimble does away with D&D’s Vancian magic system and its use of spell slots and known/prepared spells, which can be both confusing to new players and a chore to manage even for experienced players. Instead, the game uses a mana system, with spellcasters using Intelligence or Will to determine their total mana pool. Spells can be upcast by spending more mana. Nimble also does away with some of the more clunky and rarely used spells we see in D&D 5e, keeping a core list of meaningful options available that also makes it easier for players to choose what they want to do.

Notably, the Nimble 5e boxed set also contains spell cards, which are well designed and make it easy to actually keep track of specific spells without having to constantly flip through the rulebook. It’s another nice touch that fits it nicely with the game’s faster and more tactile approach to play.

Streamlined character creation

In terms of character builds, Nimble offers variety of character options, including 12 classes, 28 subclasses, 24 races and 24 backgrounds, all of which are heavily based by the standard D&D 5e options. The Commander for example, is essentially a Fighter, the Mage is a Wizard/Sorcerer, the Shepherd is a Cleric, the Cheat is a Rogue, the Songweaver is a Bard etc.

While having this many options may seem at first glance to go against Nimble’s design philosophy of a streamlined 5E, in fact the book manages to include a ton of options in an easy to digest format. A single class description in the Heroes Book for example, includes all of the class features and subclasses options on just two pages. Contrast this with Wizards of the Coast, where D&D 5e subclasses, level features and other class options can take up dozens of pages across multiple books.

Streamlined encounter and monster design

One of the biggest issues for DMs when it comes to standard D&D 5e is encounter design, with Challenge Rating being more of an inexact art than a science. Nimble’s encounter math, however, is dead simple: Total monster levels = total hero levels. This means if you have six Level-2 characters, a balanced fight is 12 levels of monsters. That’s it. No fuss, no muss, no CR guesswork.

Monster stat blocks are also incredibly streamlined and easy to use at the table. What’s more the game introduces some unique mechanics for Legendary monsters, including introducing boss battle “phases,” which function much like in a video game in that as players deal out damage, a boss gets access to unique abilities that add another layer of tactical challenge.

Compatibility and publisher support

While Nimble remains its own complete TTRPG system, it’s also incredibly flexible and fully compatible with both official and unofficial D&D 5e products. This alone makes it incredibly versatile and there’s no reason you can’t run Nimble with previously published campaigns or one shots (I plan on running a Tomb of Annihilation campaign using the Nimble boxed set).

It’s also worth noting that the Nimble rules have their own open game license along with a free creators kit, which means both fans and third-party publishers can make and sell their own Nimble 5e products.

Final Thoughts

Nimble is easily one of the best 5E-adjacent RPGs ever made and delivers on its promise of speed and tactical play without sacrificing the best parts of modern D&D. Combat flows faster. Spells feel more impactful. Actions are more meaningful. And it’s all wrapped in succinct and beautifully illustrated package.

The end result is a product that has the potential to do for 5E what Shadowdark did for the OSR, offering a version of D&D with more fun and less friction.

Final Review Score: 19 out of 20
