DnD Downtime Activities Rules
Downtime activities are the structured rules in Dungeons & Dragons for what characters do between adventures — the weeks or months when no dungeon is being crawled and no dragon is being provoked. The rules appear in the Player's Handbook (Chapter 8) and are expanded significantly in Xanathar's Guide to Everything, which introduced a dice-based resolution system that replaced much of the original flat-cost framework. For Dungeon Masters and players alike, downtime shapes the texture of a campaign world in ways that combat simply cannot.
Definition and scope
Downtime activities occupy the space between the narrative beats that usually define a session. A party returns to town after clearing a crypt — the next adventure won't begin for a month of in-world time. What happens in that month is governed by downtime rules.
The core Player's Handbook (5th edition, Chapter 8) defines downtime as a period of at least 10 consecutive days during which a character is not engaged in any other strenuous activity. The original system is deliberately lean: each activity costs a set number of days and, in some cases, gold pieces. Crafting a non-magical item costs 5 gp and 25 days of work for every 50 gp of the item's market value. Practicing a profession earns the equivalent of a modest or comfortable lifestyle without additional cost.
Xanathar's Guide to Everything substantially rewrites this framework. The 2017 supplement introduces complication tables — a dice roll that can generate consequences whether the activity succeeds or fails. Running a business, for instance, might go smoothly for 6 weeks and then produce a complication such as a supplier dispute or a competitor moving in. That small mechanical wrinkle does something larger: it makes downtime feel less like a waiting room and more like a living part of the world.

How it works
The Xanathar's system runs on a resolution sequence that can be broken into four steps:
- Choose the activity. The player declares what the character is doing — crafting, carousing, pit fighting, running a business, or one of the roughly 15 other options verified in Xanathar's Guide.
- Determine the time and resource cost. Each activity specifies a minimum number of workweeks (usually 1 workweek = 5 days). Some require a gold outlay.
- Make a relevant ability check. Most activities resolve with a single skill check — Arcana for researching a spell, Persuasion for spreading rumors, Constitution for pit fighting.
- Consult the complication table. A roll of 1–10 on a d100 (10% chance, per the Xanathar's default) triggers a complication. The DM can choose or roll randomly.
This structure keeps downtime from being purely transactional. A failed Arcana check during research doesn't just mean no progress — it might mean someone else is now asking the same questions, and they're asking them about the party.

Common scenarios
The activities most frequently invoked at actual tables tend to cluster around a few practical and narrative purposes:
Crafting (mundane and magical) — Mundane crafting uses the Player's Handbook formula (1 workweek + 50 gp of materials per 50 gp of item value). Magical item crafting in Xanathar's requires a spellcasting prerequisite, 1 workweek and 25 gp per 25 gp of the item's value, and a successful Arcana check (DC 10 for common items, scaling upward).
Training — A character can spend 250 days and 1 gp per day to gain proficiency in a tool or language. That's a 250 gp investment and a very patient character.
Carousing and pit fighting — These are the activities that generate story. Carousing (upper class, middle class, or lower class tiers carry different gold costs and different social consequence tables) produces the kind of plot seeds that DMs quietly love: unexpected allies, owed favors, public embarrassment.
Running a business — Requires ownership of a business and resolves with a Dexterity (Sleight of Hand), Charisma (Persuasion), or Wisdom (Insight) check against a DC of 20, per Xanathar's Guide. The outcome table ranges from a 10% loss to a 3d6 × 5 gp profit.
Decision boundaries
Not every downtime rule applies in every campaign, and the tension between the two official frameworks — Player's Handbook flat costs versus Xanathar's dice-based resolutions — is real.
The Player's Handbook system is faster and lower-stakes. It suits campaigns where downtime is logistical background rather than narrative foreground. The Xanathar's system takes longer to resolve but produces story material; it suits sandbox campaigns where the world continues evolving between sessions.
Complication tables are explicitly optional. The Dungeon Master's Guide (p. 125) grants DMs broad latitude to modify, skip, or invent downtime activities wholesale — the rules are a scaffold, not a statute. When a player asks whether a specific homebrew activity is "legal," the honest answer is that the rules themselves don't restrict invention; they establish a resolution model that homebrewed activities can follow.
One boundary worth knowing: downtime activities require the character to be free from adventure duties during that period. A character spending a workweek in pit fighting cannot simultaneously be scouting a dungeon. The activities are mutually exclusive with strenuous travel and combat obligations, which is a point that occasionally surprises players new to the system — the DnD frequently asked questions page addresses several of the common misreadings around timing and overlap.
