Frequently Asked Questions
Everything you need to know about using this application.
How does this random NPC generator work?
This tool utilizes a randomized array system to pull from thousands of possible combinations of race, class, personality traits, and secret backstories designed specifically for the Dungeons and Dragons 5th Edition ruleset. By utilizing logic-based weighting, it ensures that generated characters feel grounded in a high-fantasy tavern setting, providing depth and variety for any campaign. The underlying engine operates entirely in your browser's memory, ensuring that every generation is unique, lightweight, and instantaneous. It does not require a database connection or server-side processing, making it perfectly suited for quick references during a fast-paced game session where you need a tavern patron at a moment's notice.
Can I save the NPCs I generate for later use?
For security and privacy, this application does not use cookies, local storage, or server-side databases. Your generated NPCs exist only within your current browser session. If you refresh the page, the current list will be cleared, which prevents data persistence and ensures no tracking occurs. To preserve characters you enjoy, we have integrated a simple 'Copy to Clipboard' feature on every character card. This allows you to quickly paste your generated character profiles into your preferred campaign management software, text editor, or virtual tabletop (VTT) for long-term storage and reference.
Is this tool compatible with all D&D settings?
Yes, the generator focuses on standard fantasy tropes, making it highly compatible with official settings like the Forgotten Realms, Eberron, or unique homebrew campaigns. It avoids setting-specific jargon where possible to ensure maximum utility for any Dungeon Master regardless of their world-building preferences. You can interpret the output flexibly, allowing you to adapt the suggestions to fit the specific tone of your table. Whether you are running a high-fantasy adventure or a gritty, low-magic investigation, the generated traits and hooks provide a solid, creative foundation for improvisation and narrative expansion.
How do I handle this tool on mobile devices?
This application is built with a responsive, mobile-first design, ensuring that menus, character cards, and action buttons scale perfectly to fit any screen size, from smartphones to tablets and desktops. The interface is optimized for both touch and mouse input, providing a consistent experience across all platforms. We have prioritized a distraction-free, light-mode aesthetic to ensure the tool remains readable in varied lighting conditions, such as a dimly lit gaming room. All interactive elements are sized appropriately for touch screens, making it easy to create and copy NPCs on the fly while playing in person or online.
