Knave RPG Review: Classless OSR System by Questing Beast
At-a-glance: OSR lineage • d20 mechanics • Classless • Slot-based inventory • 100 spells • 3-5 players + GM • 5-min character creation • 2-3h sessions
What is Knave?
Created by Ben Milton of Questing Beast in 2018 (with a major 2nd Edition update in 2023), Knave is a rules-lite RPG built on Old-School Renaissance principles. The game strips fantasy roleplaying to its essentials: ability scores, equipment, and clever play. At just 7 pages for 1e and 80 pages for 2e, it proves that less can be more.
Knave's core philosophy is "rulings, not rules"—it gives GMs a robust framework while trusting them to make judgment calls. This approach has made it a darling of the OSR community and one of the most flexible systems for running classic D&D modules.
Core Mechanics That Matter
Slot-Based Inventory (The Secret Sauce)
Knave's signature innovation is its inventory system. Characters have 10 + CON modifier item slots. Everything occupies one slot—swords, armor, spellbooks, even wounds. When you take damage, wounds fill slots, forcing hard choices: drop the magic sword or the healing potion?
This creates natural resource tension without complex tracking. As one player noted: "The slot system adds urgency to every adventure as you steadily deplete resources."
Truly Classless Design
No fighters, wizards, or rogues here. Your character is defined entirely by:
- Ability scores (roll 3d6)
- Equipment you carry
- Spells you find (not automatic at level-up)
Any PC can cast spells if they find spellbooks. Any PC can wear plate armor. Progression comes through better gear, not level-based abilities. Want to be a spell-slinging warrior in plate? Just find the right equipment.
100 Level-Less Spells
Magic in Knave is equipment-based. Spells are contained in books, each occupying a precious inventory slot and usable once per day. The 100 included spells scale with cleverness, not character level—"Manipulate Fire" might light a candle or create a wall of flames depending on player ingenuity.

| Best For | Ultra-light play | GMs who love generators |
Why Players Love It
As a Standalone Game: Character creation takes literally 5 minutes. Roll stats, pick gear from starting packages, and you're exploring. The unified d20 mechanic (roll high, add bonus) is immediately intuitive for D&D veterans and newcomers alike.
As a GM Toolkit: Even when running other systems, many GMs keep Knave at their table for the random tables. Need a dungeon? Roll on the dungeon generator. Need a faction? There are tables for that. One GM noted: "I use Knave's tables even when running D&D 5e."
Who Is Knave For?
- New TTRPG Players: The minimalist rules mean you spend more time playing than learning.
- Experienced GMs: The procedural generators support improvisation and reduce prep time.
- Solo Players: The random tables make Knave excellent for solo RPG sessions.
- OSR Veterans: Compatible with B/X, AD&D, and modern OSR adventures with minimal conversion.
Practical Limitations
Knave intentionally leaves gaps. There's no default setting—you bring your own world. The focus on gear over character abilities means some players miss class-based progression. And the rulings-over-rules approach requires confident GMing.
Some players also critique the Wisdom-based ranged attacks and the outsized importance of Constitution for inventory. These are minor quirks in an otherwise elegant system.
FAQ
Is Knave free?
Knave 1e is $3 on Itch.io. Knave 2e is $15 PDF or $30 for the hardcover.
Can I use Knave with D&D modules?
Yes—Knave is designed for compatibility with any B/X, AD&D, or OSR adventure. Monsters, treasure, and dungeons convert easily.
How long does character creation take?
About 5 minutes. Roll stats, choose starting equipment packages, and begin playing.
Is Knave good for one-shots?
Excellent. Fast character creation and deadly combat make it perfect for convention games or single sessions.
What's the difference between Knave and Cairn?
Both are slot-based OSR games, but Cairn emphasizes survival horror while Knave focuses on dungeon delving and exploration. Knave has more robust procedural generators; Cairn has a more defined grim tone.
The Bottom Line
Knave proves that OSR design doesn't mean complex rules. Its slot-based inventory creates meaningful decisions every session. Its classless system encourages creative character builds. And its 100 spells reward clever play over character optimization.
Whether you're a new player looking for your first RPG or a veteran GM wanting the ultimate toolkit, Knave delivers. As the 2nd Edition expanded into an 80-page generator powerhouse, it evolved from a minimalist curiosity to an essential OSR resource.
