donjon

Overview

donjon is a legendary, minimalist suite of web-based procedural generators that has served as the "Swiss Army Knife" for Game Masters since its first dungeon generator went live in 1999. Created and maintained by a developer known as drow, the site eschews modern flashy graphics and subscriptions in favor of raw utility and speed. In late 2025 and 2026, the site saw a significant "5.5 Refactor," adding full support for the 2024 D&D Core Rules, including new treasure tables, encounter calculators, and Bastion event generators. Description donjon is the ultimate tool for the "Zero-Prep" GM. It is a collection of text and image-based algorithms that can generate everything from a single NPC to an entire star system in less than a second. While newer tools focus on 3D visuals, donjon remains a favorite because it is incredibly lightweight; it loads instantly on any device and provides high-density information without any clutter. It is the "source code" of many GMs' campaigns, providing the mechanical backbone for loot, encounters, and world-building data. System Overview & Key Features
Random Dungeon Generator The crown jewel of the site. It creates fully mapped-out dungeons with "old-school" aesthetics. You can specify the level, layout, and "dungeon motif" (like Sunken Temple or Abyssal Rift), and it will populate the map with traps, secret doors, wandering monsters, and room descriptions automatically.
D&D 5.5 / 2024 Core Support New for 2026, the site features a dedicated "5.5" section. This includes an updated Encounter Size Calculator that accounts for the 2024 power scaling, as well as a Magic Shop Generator that utilizes the new pricing and item rarity structures introduced in the latest D&D revision.
Fractal World Generator This tool uses a recursive algorithm to generate entire world maps with realistic coastlines, islands, and tectonic-like features. GMs can adjust the "Ice Limit," "Water Percentage," and "Scale" to create a unique continent or a planet-wide archipelago in seconds.
Sci-Fi and Weird Fiction Suites Beyond fantasy, donjon is the premier source for Star Wars (d6/d20) and Traveller star system generators. It also features a Weird Fiction section for Call of Cthulhu players, generating eldritch tomes, blasphemous rituals, and sanity-testing NPCs.
The "Endless Oubliette" For GMs running "Megadungeons," this tool uses Dyson Logos-style geomorphs to generate an infinitely expanding dungeon. As players move through the map, the GM can keep generating new sections, ensuring the dungeon literally never ends.
HTML and TSV Exports Almost every generator on the site allows you to export results as a raw text file or a portable HTML page. This is essential for GMs who want to copy-paste generated NPCs directly into Discord or import loot tables into Foundry VTT or Obsidian.

Pathfinder 2nd Edition is a tactical, crunchy and highly customizable heroic fantasy roleplaying game system published by Paizo. Originally released in 2019 as the evolution of the Pathfinder system (which grew out of the D&D 3.5 system, as a reaction to the release of the simplified and more video game-like D&D 4E). The system recently received a comprehensive "Remaster" overhaul, which decoupled the game from the legacy Open Game License (OGL), moving it to the system-agnostic ORC License. The Remaster version has updated various terminology and streamlined different conflicting mechanics, the core engine of PF2E remains exactly the same as before. Description Like other d20-based fantasy games, players are an adventuring party that go on adventures, defeat enemies and uncover various mysteries while the Game Master (GM) is in charge of running the world around the characters and is in control of managing any enemies and non-player characters they might encounter. However, where D&D 5E leans heavily on "rulings over rules" and simplicity, Pathfinder 2E has shifted its focus on customization and making sure that with every system balance is maintained. Pathfinder 2E is ideal for players who are more into tactical combat, clear rules for exploration, and the ability to build unique character concepts with a reasonable amount of customization without accidentally breaking the game or worry too much about maintaining balance. The system comes with great tools for the GMs as the system provides clear guidelines and mechanics for most situations, meaning the GM rarely has to invent or interpret rules on the fly to keep the game moving. System Overview & Key Features The 3-Action Economy Pathfinder 2E is famous for their action system. Instead of pre-defined action types, the player can perform creatively distribute their actions how they see fit. Instead of always having a "move action" that the character can utilize or leave unused, the system allows a character to instead use that action as an extra attack. Or instead of attacking, the adventurer can move twice (or thrice, if using all actions). Degrees of Success Instead of approaching "1" or "20" on the d20 die as a critical result, The system considers "oversucceeding" as a critical success. Succeeding a roll by 10 or more points it is automatically a Critical Success. If you miss the DC by 10 or more, it is a Critical Failure. Because of this, every single +1 or -1 improvement feels more impactful and important. Feat-Based Character Customization There are no "useless level-ups" Every single level-up players make meaningful choices by selecting from an extensive assortment of Ancestry Feats, Class Feats, Skill Feats, and General Feats. This creates a situation, where even two characters of the same class can be played completely differently. Reliable Encounter Building The game's underlying math is rigorous and highly functional. An encounter mathematically classified as "Severe" will actually push the party to their limits. GMs can trust the system's encounter building rules completely. Keyword and Trait System Spells, weapons, and abilities have specific traits (like "Incapacitation" or "Fire"). If a rule has a trait, it consistently interacts with the rest of the game's mechanics in the exact same way, removing ambiguity. Edicts and Anathema PF2e has abandoned the traditional moral alignment system. Deities and classes are governed by Edicts (things your character must strive to do) and Anathema (things you must avoid), creating a more nuanced approach to roleplaying.
