Backgrounds and Feats: Rules Guide
Backgrounds and feats are two of the most character-defining mechanical levers in Dungeons & Dragons 5th Edition — the choices that separate a generic fighter from someone with a particular history, a specific skill set, and a combat trick nobody else at the table has. This page covers how backgrounds and feats work under the rules, how they interact, and where the tricky judgment calls tend to land. Whether a player is building a first character or optimizing a fifth, the rules here repay careful reading.
Definition and scope
A background represents what a character did before adventuring began. Under the 5th Edition rules as published in the Player's Handbook, each background grants a fixed package: 2 skill proficiencies, a tool or language proficiency, starting equipment, and a narrative feature that creates social or environmental advantages in play. Examples include Criminal, Sage, and Folk Hero — each anchored to a specific pre-adventuring life.
A feat is an optional rule, explicitly flagged as such in the Player's Handbook (Chapter 6), that allows a character to trade an Ability Score Improvement for a discrete mechanical benefit. Common feats include Alert (a +5 bonus to initiative), War Caster (advantage on concentration checks), and Sharpshooter (negating long-range penalties). Feats range from minor ribbons to significant combat multipliers, and the Dungeon Master has final authority over which feats appear in a given campaign.
The scope distinction matters: backgrounds are mandatory at character creation and not revisited. Feats are optional enhancements that arrive at levels 4, 8, 12, 16, and 19 for most classes — the same levels that offer Ability Score Improvements. A character can have a background but zero feats, which is perfectly legal under the standard rules. For a broader look at how these choices fit into character building generally, the key dimensions and scopes of DnD page maps the full landscape.
How it works
Backgrounds slot in at character creation in a specific sequence:
- Note the background feature (e.g., Criminal's Criminal Contact, Sage's Researcher) and its narrative function.
- Take the verified starting equipment or the standard gold option, as the DM permits.
Feats operate differently, arriving as a choice rather than an assignment. At each Ability Score Improvement level, the player chooses either to raise one or two ability scores (up to the 20 cap) or to take a single feat. Most feats carry a prerequisite — Heavily Armored requires proficiency with medium armor; Spell Sniper requires the ability to cast at least one spell. If the prerequisite isn't met, the feat is unavailable.
The how it works page goes deeper on the general mechanical framework, but the key procedural point is this: background choices are locked in at level 1, while feat opportunities recur throughout a character's career. A player who regrets skipping War Caster at level 4 gets another chance at level 8.
Common scenarios
Stacking proficiencies. A Rogue with the Criminal background already has Stealth from the class list. The background also grants Stealth — so the player swaps it for another skill on the class list. This comes up constantly and is one of the first character-creation friction points new players hit.
The Variant Human feat. The Player's Handbook presents the Variant Human as a subrace that grants a free feat at level 1. This is the only standard way to enter play with a feat already in hand, and it's a popular choice precisely because level 4 can feel far away. A Variant Human Fighter with the Sentinel feat enters their first session with the ability to stop enemy movement on a reaction hit — a significant early-game edge.
Custom backgrounds. The Player's Handbook (p. 125) explicitly permits players and DMs to build custom backgrounds, provided they follow the same package structure: 2 skills, 1–2 tools or languages, equipment, and a feature. Custom backgrounds are common in homebrew campaigns and should be reviewed by the DM before play.
Half-feats. Some feats — Actor, Durable, Observant — grant a +1 to an ability score alongside their special rules. These are sometimes called "half-feats" in player shorthand (though that term doesn't appear in the official rules). They let players split the difference between raw stat improvement and mechanical variety.

Decision boundaries
The clearest decision boundary is background vs. backstory. The rules define what a background grants mechanically. The narrative attached to it — why a character was a criminal, which guild a sage studied under — is player-authored fiction that has no mechanical weight unless the DM rules otherwise. This distinction prevents confusion when players expect their backstory to confer advantages not present in the rules text.
The feat vs. Ability Score Improvement trade-off is genuinely consequential. A +2 to Strength raises attack rolls, damage, and saving throws for every combat encounter going forward. Sentinel stops one enemy once per round. Neither choice is universally correct — it depends on the character's role, the campaign's length, and the DM's encounter design. Melee-focused characters in campaigns that run to level 12 or higher often find the math tips toward ability scores in the mid-levels, while casters frequently prioritize War Caster or Resilient (Constitution) as their first feat pick to protect concentration spells.
Background features, by contrast, are DM-adjudicated rather than mathematically modeled. The how to get help for DnD page covers where to bring disputes when table interpretations diverge. When in doubt, the Player's Handbook text governs — and the DM's ruling at the table governs the Player's Handbook.
