One Realm is an AI-assisted campaign workspace and virtual tabletop built for groups that want to play tomorrow—not spend the week preparing. It turns adventures, source material, and campaign notes into an organized, playable world, helping GMs complete work that might otherwise take hours or days in a matter of minutes. Characters, locations, encounters, maps, relationships, and story events are automatically organized and connected. From there, the GM can prepare scenes, create artwork, manage characters, and run the game through the integrated virtual tabletop. Because everything shares the same campaign context, preparation flows directly into play without rebuilding the session across multiple tools.

RPG Map is a free, browser-based map viewer built around gradual map reveal — Fog of War. It's not a map-making suite and doesn't try to be one (for creating maps, tools like Dungeondraft or Watabou's generators are a better fit). Instead, it focuses on one thing: taking a finished map and revealing it to your players piece by piece, in person or online. The GM loads a map and shares a link. Players open it on any device — laptop, tablet, or phone — and everything stays in sync in real time: as the GM erases fog, moves tokens, or pans the view, players see it instantly. No installation, no account, no ads, and no fees. Features: Fog of War — reveal the map gradually with a simple brush and eraser Realtime synchronization — players follow the GM's reveals live via a shared link Drag & drop tokens — place and move character and monster tokens on the map Automatic grid detection — the grid aligns to your map without manual setup Built-in library — free maps and tokens to get started right away Mobile ready — works in the browser on phones and tablets, nothing to install Whether you play at a physical table with a shared screen or fully online, RPG Map keeps setup to seconds: open, load, reveal.

Dungeons & Dragons 4th Edition is a tactical, combat-focused tabletop roleplaying system released by Wizards of the Coast in 2008. Designed to fix the high-level math imbalances and "martial vs. caster" disparities of the 3.5E era, 4E redesigned the game's engine with a more video game adjacent approach. It is famous for its structured, grid-based combat and for standardizing class abilities into a unified system. While its dramatic departure from legacy mechanics polarized the fanbase directly paving the way for the creation of Pathfinder. 4E is widely praised today for its brilliant monster design, DM tools, and unparalleled encounter balance. The system it directly replaced is Dungeons & Dragons 3.5 Edition (2003) Description In D&D 4E, players take on the roles of heroes who are combat-capable right from the start. The system relies of combat being carried out with the use of a battle grid. Positioning plays a big part of the combat experience. The exact location of the characters matters greatly. Unlike other editions where spellcasters are played in a separate mechanical way than martial classes, 4E unifies the progression system. Every class is boiled down to a specific combat "Role" and draws from their specialized toolkit of "Powers," making the game balanced and ensuring that every character has unique and impactful actions that they can perform on their turns. System Overview & Key Features The Power System Instead of traditional spell slots or basic attacks, every class has a list of At-Will, Encounter, Daily, and Utility powers, each with different power levels and frequency at which they can be performed. Fighters can execute epic daily maneuvers just as wizards cast daily spells, creating a better balance between martial classes and spellcasters. Combat Roles All classes are sorted by their class specialization role: Defenders (tanks who draw aggro and protect their allies), Strikers (high single-target damage), Leaders (healers and support), and Controllers (area-of-effect damage and debuffers). Static Defenses Saving throws were removed and replaced with four different defense values: Armor Class, Fortitude, Reflex, and Will. When a wizard casts a fireball, they roll an attack against the targets' Reflex. Instead of both sides rolling for success and for defense - the attacker is the only one to roll dice. Healing Surges A standardized resource pool representing a character's stamina. Almost all healing in the game, whether from a cleric's spell or catching your breath, requires the target to spend a Healing Surge, which reliably heals them for exactly one-quarter of their maximum hit points. Monster Roles & Minions The Dungeon Master's toolkit was revolutionized. Monsters have explicit roles (like Brute, Artillery, or Skirmisher) that cleanly dictate their behavior. 4E also introduced "Minions". Monsters that have normal stats and deal average damage, but only have exactly 1 Hit Point, allowing heroes to cleave through cinematic hordes. Skill Challenges An unique system with 4E is Skill Challenges - a "cinematic" series of actions that turn social, environmental or escape situations into more movie-like scenes. The players must achieve a certain amount (determined by the situation) of successful skill checks, before they collect enough failed skill checks.

DC20 is a fantasy tabletop RPG designed by Alan Bjorkgren, a former high school math teacher and track coach better known online as The Dungeon Coach, where he spent years producing D&D 5e homebrew content before deciding to build his own system outright - a decision accelerated by Wizards of the Coast's 2023 OGL controversy.  Rather than reinventing fantasy TTRPGs from scratch, DC20 keeps 5e's basic silhouette - classes, levels, a d20 core - while substantially rebuilding the parts Bjorkgren felt were holding the format back: action economy, damage resolution, spellcasting, and character customization. Its June 2024 Kickstarter broke $1 million within its first week, and the game has been in active public beta ever since, currently on Core Rules Beta 0.10.5, with the full Core Rulebook still pending release.
