DND: Frequently Asked Questions
Dungeons & Dragons has accumulated more than 50 years of rules, editions, errata, and table traditions — which means the question pile is enormous and genuinely interesting. This page addresses the questions that come up most often, from mechanical basics to the kinds of edge cases that tend to spark 45-minute debates between sessions. The goal is plain, accurate answers grounded in the published rules, not house-rule folklore.
What does this actually cover?
The scope here is Dungeons & Dragons as a tabletop roleplaying game, with primary focus on the 5th Edition ruleset published by Wizards of the Coast — the edition most active tables use since its 2014 release. That said, questions about earlier editions (particularly 3.5 and 4th Edition) surface often enough to merit occasional comparison. The rules themselves live across three core books: the Player's Handbook, the Dungeon Master's Guide, and the Monster Manual. Supplemental material — adventure modules, setting guides, and optional rule expansions in books like Xanathar's Guide to Everything and Tasha's Cauldron of Everything — layer on top of that foundation. The main reference hub organizes these categories if a specific subsystem is the destination.
What are the most common issues encountered?
Four problem areas account for the majority of rules disputes at active tables:
- Action economy confusion — the distinction between Actions, Bonus Actions, Reactions, and Free Actions is precise in the rules but easy to blur during fast play.
- Concentration stacking — players frequently attempt to maintain two concentration spells simultaneously, which the rules prohibit (Player's Handbook, Chapter 10).
- Opportunity Attack triggers — specifically, which movements do and do not provoke them (Disengage, forced movement, and teleportation do not).
- Multiclassing prerequisites and spell slot calculations — the proficiency and ability score minimums, and the way spell slots are pooled rather than tracked per class.
The Sage Advice Compendium, maintained by Wizards of the Coast at sageadvice.eu as a community archive and officially at dnd.wizards.com, addresses a substantial portion of these directly with designer rulings.
How does classification work in practice?
D&D material is organized into three broad tiers: core rules, official supplements, and third-party content. Core rules (the three main books) carry the most weight at any table. Official supplements are considered opt-in — a Dungeon Master decides whether Xanathar's Guide feats or Tasha's subclasses are available in a given campaign. Third-party content published under the Open Game License (OGL) or the newer Creative Commons SRD 5.1 release operates in a separate category: legal to produce and use, but not binding on any table without explicit agreement. The System Reference Document 5.1 is freely available under Creative Commons Attribution 4.0, a licensing shift Wizards of the Coast formalized in 2023.
What is typically involved in the process?
Running a D&D session involves preparation distributed across two roles. The Dungeon Master prepares the setting, non-player characters, encounters, and narrative framework. Players build and track characters using the rules in the Player's Handbook, including:
A standard session runs 3–4 hours, though organized play events like the Adventurers League use a structured 2-hour format. The Adventurers League, D&D's official organized play program, publishes its own Player's Guide each season with specific character-building restrictions that differ from home table norms.
What are the most common misconceptions?
The most durable misconception is that the Dungeon Master's ruling is somehow in conflict with the written rules — when in fact, the Dungeon Master's Guide explicitly grants DMs authority to modify rules. Rule 0, as it is informally known, is not a workaround; it is in the book. A second widespread misread: Passive Perception is not only used when a character is distracted or inactive. The rules specify it as the floor for noticing things without an active check, always in effect. Third, Inspiration — the reward mechanic — does not stack. A character either has it or does not; a second award from the DM simply confirms the existing state.
Where can authoritative references be found?
The primary official sources are the published hardcover rulebooks and the freely downloadable SRD 5.1 (available at creativecommons.org for the license terms and directly from Wizards of the Coast for the document). The Sage Advice Compendium consolidates official designer rulings and is updated periodically. D&D Beyond, the official digital toolset at dndbeyond.com, integrates licensed rule text and is owned by Wizards of the Coast as of its 2022 acquisition.
How do requirements vary by jurisdiction or context?
Context here means play format rather than geography. Home games have no external requirements — the table sets its own norms. Adventurers League play operates under a separate document set, with rules for content legality, character rebuilding, and magic item acquisition that change seasonally. Convention games run by independent organizers may use modified encounter-building guidelines. Age appropriateness is addressed informally through content ratings on official published adventures: the Dungeon Master's Guide and products like Curse of Strahd carry a suggested age of 13 and up, though no binding standard governs this.
What triggers a formal review or action?
Within Adventurers League play, character audits can be triggered when a player's character sheet does not match the logged play history in their Adventure Log — the paper or digital record of sessions, rewards, and magic items. Discrepancies discovered at the table result in the character being set aside until the log is reconciled. At home tables, the equivalent moment is a session zero disagreement about house rules — specifically, rules introduced mid-campaign that retroactively affect existing characters. The Dungeon Master's Guide recommends establishing expectations before play begins precisely to prevent this kind of friction from interrupting an ongoing story.
