How to Create Your Own Random Table or Generator on Chartopia

You can create a custom random table or generator on Chartopia by signing in, opening the Create Chart entry from the site navigation, and building your table there. This works for any tabletop RPG system, since Chartopia is system-agnostic: it hosts random tables and generators for NPCs, locations, encounters, names, loot, spells, monsters, and more. The only prerequisite is an account — the site exposes Sign In and Create Account links, so plan on registering before you build anything.

What Chartopia Gives You

Chartopia describes itself as a place to "discover, create and manage your random table and random generator collection." The pitch is that you can leave your massive book collection at home and let the platform handle the dice rolling so you can concentrate on the story.

Two things follow from that description:

• Creation and management are both part of the product. You are not just rolling on other people's tables; you are maintaining your own collection.
• The output is meant for play. Tables are built to be rolled during a session, not just stored.

Step-by-Step: Building Your First Table

1. Create an account or sign in. Use the Create Account link if you are new, or Sign In if you already have one. You need to be authenticated before your charts can be saved and managed.
2. Open Create Chart. This is the site's dedicated entry point for authoring a new table or generator. It sits in the same navigation as Sign In, Create Account, Contact, and Help.
3. Define the table's rows and outcomes. Each row is a possible result. For a simple table, one roll maps to one row. For a generator, you chain or nest tables so a single roll produces a richer result.
4. Save the chart. Once saved, it becomes part of your collection and can be rolled like any other chart on the site.
5. Roll it to verify. Run the chart and check that the results match what you intended before you rely on it at the table.

The exact field layout inside the Create Chart editor is not described in the site material available here, so treat the steps above as the workflow rather than a click-by-click map of the form.

Learn the Structure from Existing Charts

The fastest way to understand how a Chartopia table is put together is to look at published examples. The homepage surfaces Featured Charts and Latest Charts, and each entry shows a title, an author, and a roll count. A few concrete examples from the site:

Two patterns are worth copying:

• Version your generators. The vampire generator carries "v1.23" in its title, which tells you the author iterates on it over time.
• Credit your sources. Several featured charts link to the blog, icon set, or book they drew from. Some tables, like the Tome of Adventure Design entries, even cite the page number they were adapted from.

Collections: Grouping Related Tables

Chartopia also has Collections, which bundle related charts together. The homepage lists Featured Collections and Latest Collections, with examples such as Fatebenders generators, Starforged Oracles, Zombie's Vampire the Masquerade V5 Collection, Stars Without Number - Revised (Free Edition), and Moldvay Basic D&D Treasure Types.

If you are building more than one table for the same campaign or system, a collection is the natural way to keep them together and to share them as a set.

Finding and Reusing What Already Exists

Before you build from scratch, check whether someone has already made it. The site provides:

• Quick search with shortcuts for NPCs, Locations, Encounters, Name generators, Loot, D&D 5e Spells, and Monsters.
• Latest Charts and Latest Collections for browsing recent additions.
• Featured Charts and Featured Collections for curated picks.

If a published chart is close to what you need, studying its structure is a legitimate starting point for your own version — just credit the original if you adapt it, the way the featured charts do.

Common Stumbling Blocks

• Trying to build before signing in. The Create Chart flow assumes an account. Register first.
• Making one giant table instead of nesting. Generators that combine several smaller tables (a name table, a behavior table, a loot table) are easier to maintain and reuse than a single sprawling list.
• Not testing the roll. A table that looks right in the editor can still produce odd combinations. Roll it several times before using it live.
• Forgetting to organize. Once you have more than a handful of charts, a collection keeps them findable.

What You Can Build

Given the categories the site itself highlights, your custom table can cover NPCs, locations, encounters, names, loot, spells, and monsters — or anything else your game needs. The platform is not tied to one ruleset, so the same Create Chart workflow applies whether you are running D&D 5e, Vampire: The Masquerade, Stars Without Number, or a homebrew system.
