Dungeons & Dragons 4E (2008)

Dungeons & Dragons 5th Edition (D&D 5E) is a heroic fantasy tabletop roleplaying game published by Wizards of the Coast. Released in 2014, it is the edition that brought D&D from a niche hobby into mainstream pop culture - showing up in TV shows, podcasts, and actual-play streams, and introducing millions of new players to the hobby for the first time. 5E was designed after a massive public playtest ("D&D Next") with the explicit goal of being approachable to newcomers while still satisfying veteran players. The Basic Rules are free, and a game can start with nothing more than those rules, some friends, and a set of dice (or a digital dice roller app). In 2024 the core rules received a significant revision, now commonly referred to as Dungeons & Dragons 5.5E (2024). Both versions are fully compatible and most groups mix material freely. The system it directly evolved from is Dungeons & Dragons 4E (2008) Description In D&D 5E, players create fantasy adventurers (a half-orc barbarian, an elven wizard, a tiefling rogue) and one player takes on the role of the Dungeon Master (DM). The DM builds and describes the world, voices the non-player characters (NPCs), controls the monsters, and acts as both the lead storyteller and the rules referee. There is no board. The game is a conversation: the DM describes a scene, the players say what their characters do, and the dice decide what happens when the outcome is uncertain. A typical session runs three to four hours with a group of three to six players plus the DM. The game describes itself as resting on "Three Pillars": Combat, Exploration, and Social Interaction. A single session might include all three, from tracking a monster through the wilderness and negotiating with a shady merchant to fighting a troll at the entrance to a cave. Combat is the most mechanically detailed of the three and tends to take up the largest share of table time, though groups are free to lean as hard into roleplaying or exploration as they like. The default assumption is a high-fantasy world filled with magic, monsters, and ancient ruins. The flagship published setting is the Forgotten Realms, but Wizards of the Coast has released adventures across a range of worlds, and many DMs create their own. The game does not ship a single canon story. Every table's story is different, shaped by what the players do. 5E is designed to be approachable. The core philosophy is "rulings over rules," meaning that when something comes up that the rules do not explicitly cover, the DM is encouraged to make a quick call and keep the game moving rather than stopping to look things up. The rules reward creativity and improvisation, and the system explicitly expects that no one at the table has memorized the entire rulebook. That said, the DM carries most of the preparation work between sessions: building encounters, preparing maps, and keeping the story moving. Players can show up with nothing but their character sheet and a set of dice.

Dungeons & Dragons 5.5E (commonly called the "2024 rules" or "D&D 2024") is the revised and updated version of the Dungeons & Dragons 5th Edition tabletop roleplaying game, published by Wizards of the Coast. Released across three core rulebooks throughout 2024 and early 2025, it is not a new edition. It is the same game, refined. The revision was driven by a decade of player feedback and data on how tables actually run 5E, and it shipped to coincide with the game's 50th anniversary. The three revised core books are the Player's Handbook (September 2024), the Dungeon Master's Guide (November 2024), and the Monster Manual (February 2025). All three are reorganized, reworded for clarity, and mechanically updated. Rather than replacing 5th Edition with a "6th Edition," 5.5E expands and tightens the existing framework while maintaining backwards compatibility with every 5E adventure module, sourcebook, and campaign setting published since 2014. If you are new to D&D entirely, start with the Dungeons & Dragons 5e (2014) entry for a full explanation of how the game works. Everything described there still applies here. This entry covers what 5.5E specifically changed. Description D&D 5.5E plays identically to 5th Edition at the table. Players create adventurers, one player takes on the role of the Dungeon Master (DM), and the group tells a collaborative story driven by a twenty-sided die (d20) and the DM's rulings. The core loop, the "Three Pillars" of Combat, Exploration, and Social Interaction, and the fundamental mechanics (Advantage and Disadvantage, Bounded Accuracy, the Proficiency Bonus, the rest system) all carry over unchanged. What the 2024 revision addresses is the rough edges that a decade of play exposed. Martial classes (Fighters, Barbarians, Monks, Rogues) now have more tactical options in combat instead of repeating the same basic attack every turn. Spellcasting classes have been rebalanced to reduce the gap between low-level and high-level power. Rules that were famously unclear or frequently house-ruled (grappling, crafting, surprise, two-weapon fighting) have been rewritten. The Dungeon Master's Guide, long criticized as poorly organized, has been restructured into a book that new DMs can actually learn from rather than only reference. The result is a game that feels the same at the table but runs more smoothly. Groups that have been playing 5E for years will notice the quality-of-life improvements. Groups starting fresh will simply have a cleaner ruleset from day one. Both 2014 and 2024 material can be used at the same table without conversion, though the newer rules are recommended for new characters.

Daggerheart is a fantasy tabletop role-playing game published by Darrington Press, an imprint of Critical Role Productions. The game was released in 2025. Description Daggerheart is a story-docused role-playing game system, where the rules direct players to think narratively and not just mechanically. The game uses a system called Duality Dice, where players roll two twelve-sided dice. One for Hope and one for Fear. In addition to determining whether the character achieves success or fails at the action they are trying to perform, it also generates a helpful Hope resource for the player, or a challenging Fear resource for the game master (GM). Lead designer Spenser Starke explained that there is "also no initiative in Daggerheart". It functions very much like a Forged in the Dark or a Powered By The Apocalypse game, where the GM is making moves on certain dice rolls and we're passing play back and forth as a conversation. It all flows together in a way that supports the storytelling-first direction that Critical Role has really embraced over the last decade". The game features 279 supplemental cards to track player abilities and characteristics. Darrington Press also launched several digital resources, including an online custom card creator.

Forge Steel is a community-developed, locally-hosted web application and digital utility designed for Draw Steel, the cinematic fantasy tabletop role-playing game created by MCDM Productions. Developed by independent community members during the game's playtest phase, the application functions as a lightweight encounter builder and combat manager. It is specifically built to assist Directors in organizing game data and tracking real-time combat statistics during a session. Description Forge Steel serves as a digital toolkit for preparing and executing combat encounters in Draw Steel. In contrast to cloud-based alternatives, Forge Steel relies on local browser storage. This means the application does not require users to create an account or rely on external servers to save their data. All created encounters, customized monsters, and campaign notes are stored directly within the cache of the user's web browser. This architecture prioritizes data privacy, offline accessibility, and fast load times, though it requires manual file exporting to transfer data between different devices. System Overview & Key Features Local Storage Architecture The application operates entirely within the user's web browser without communicating with a backend database for everyday use. Because it utilizes local storage, no login credentials are required. This ensures the tool remains highly responsive and can continue to function even if the user loses their internet connection during a game session. Encounter Construction Directors can use the tool to design combat encounters by selecting monsters from an integrated database. The application automatically calculates the total Encounter Value, allowing the Director to balance the difficulty of the fight against the level and size of the player character party. Active Combat Tracking During gameplay, Forge Steel provides a dashboard to manage the flow of combat. It tracks essential Draw Steel mechanics, including monster Stamina, current initiative groups, temporary status effects, and the accumulation of Villain Power. This centralized view reduces the amount of physical bookkeeping required by the Director. Integrated Bestiary The application includes a searchable bestiary containing the official monsters released during the Draw Steel playtest and early access periods. Directors can quickly filter these creatures by role, level, or faction, and view their complete stat blocks, abilities, and passives directly within the app. Import and Export Functionality To mitigate the limitations of local-only storage, Forge Steel includes manual data management tools. Users can export their prepared encounters, custom bestiaries, and campaign data as JSON files. These files can then be saved as backups or imported into Forge Steel on a different computer or browser, allowing for manual cross-device syncing. Homebrew Integration Directors have the ability to manually input and modify monster statistics. This allows users to create custom adversaries or tweak existing official monsters to fit their specific campaign needs. These custom entries are saved locally alongside the official bestiary.

Released in 2014 by Chaosium, Call of Cthulhu 7th Edition is the latest version of the cult-classic cosmic eldritch horror role-playing system originally launched in 1981. The story is based off of the  literary works of H.P. Lovecraft and lovecraftian works. Instead of setting the players up as heroes, the characters are regular investigators who are exploring cults, forbidden knowledge and various eldritch-cosmic entitites and threats. Description Occupations in the game for the characters include academics, reporters, and private investigators. The gameplay loop revolves around uncovering information, analyzing clues, and evading dangers. As the supernatural elements in the game are considered more powerful than the investigators, they have are not expected to actually confront most of the threats head on. Instead they usually have to resort to avoiding or escaping any situation that may arise. Combat is lethal and usually leads to characters getting permanently killed or pushed to insanity (which eventually is the same).  System Overview & Key Features Percentile Framework (d100) Every action is resolved by rolling two ten-sided (d10) dice to get a result from 1 to 100. If you roll is equal to or under your skill rating, the action is deemed a success. This approach simplifies the mechanical process of the game, as there are no complex tables to keep track of and compare to decypher whether it is a success or failure. Pushed Rolls If a character fails a skill check, they may attempt to "push" the roll, allowing for a second attempt. This requires the player to come up with a new, more desperate approach to performing the task. If this subsequent pushed roll also fails, the Keeper describes a severe and immediate negative consequence. Sanity and Madness A core mechanic of the system is the tracking of mental stability. Investigators lose points from their Sanity gauge when exposed to anomalous creatures or disturbing truths. Drops in Sanity result in the character experiencing temporary or permanent forms of madness, which can manifest as new phobias, delusions, or a temporary loss of player agency over the character. Bonus and Penalty Dice To account for situational advantages or disadvantages, the game employs a system of bonus and penalty dice. If a character possesses a distinct advantage when performing a task, an extra d10 is rolled and taking the higher result. A disadvantage means rolling an extra d10 and taking the lower result. Combat Lethality Physical altercations are inherently dangerous by design. Investigators possess limited hit points, and the damage output of both conventional firearms and anomalous entities is high. Recovery mechanics are slow, simulating realistic healing times. This structural lethality serves to discourage combat and incentivize stealth and investigation. Expendable Luck Players can spend points from their character's Luck pool to retroactively lower a dice roll. The points are subtracted on a one-to-one basis until the dice result qualifies as a success. This ensures that the Luck pool is a limited resource which should be used and utilized in the most critical situations.

Rollful is a hosted dice-rolling API. It rolls dice over HTTP: a request carries a formula, and Rollful parses it, rolls each die through a cryptographically secure generator, and returns every die it rolled rather than only the total. It is not tied to any game system. It knows what 4d6kh3 means and nothing about what the caller uses it for, so it suits a virtual tabletop, a character sheet, a Discord bot, or anything else that needs a roll it can show the working for. The formula grammar covers flat modifiers, advantage and disadvantage, keeping the highest or lowest dice, exploding and penetrating dice, multipliers, several terms in one roll, and tags. The response lists every die with a flag saying which ones counted, so an interface can show the die a keep rule dropped instead of hiding it. A GET request handles a plain formula. POST adds bonuses and tags, and a batch endpoint takes up to 20 rolls in one request. Every response and error has the same documented shape, described by an OpenAPI 3.1 document. There is no account and no API key. Usage is rate limited rather than metered. The homepage carries a form for rolling dice straight from the browser. Rollful is powered by the OpenDice npm package, which is free to use directly in any JavaScript or TypeScript project.
