DnD Feats: Rules and Full List
Feats are one of the most powerful levers a player can pull in Dungeons & Dragons 5th Edition — optional character upgrades that trade a core stat increase for a specialized ability, trick, or combat style. The rules governing feats appear primarily in the Player's Handbook (2014) and have been significantly expanded in Tasha's Cauldron of Everything (2020). Understanding how feats work, when they're available, and how they interact with other character-building choices is central to getting the most out of any long-running campaign.
Definition and scope
A feat in D&D 5e is a discrete rules package that grants a character one or more specific mechanical benefits — things like new attack options, skill proficiencies, spellcasting access, or ability score improvements attached to conditions. Feats are explicitly optional, as stated in the Player's Handbook Chapter 6: Dungeon Masters and table groups can choose to exclude them entirely without breaking the core ruleset.
The distinction between feats and class features is worth keeping sharp. Class features are mandatory acquisitions that arrive on a fixed schedule — a Fighter gets Action Surge at level 2, no debate. Feats, by contrast, require a deliberate trade-off and are never guaranteed. They arrive at specific character advancement milestones and always compete with something else valuable. That competition is the whole design tension feats create, and it's not accidental.
As of Tasha's Cauldron of Everything, the rules also introduced a new category: Origin Feats and Half-Feats, a term the community uses for feats that include a +1 bonus to an ability score alongside their special ability. Examples include War Caster, which requires Constitution, Intelligence, or Wisdom spellcasting, and Resilient, which grants proficiency in a saving throw of the player's choice plus a +1 to the associated ability score.
The key dimensions and scopes of DnD page covers how feats fit into the broader character-building ecosystem alongside spells, subclasses, and multiclassing.
How it works
Feats become available at Ability Score Improvement (ASI) levels — the character levels at which classes grant the option to increase ability scores. For most classes, ASIs arrive at levels 4, 8, 12, 16, and 19. Fighters receive additional ASIs at levels 6 and 14; Rogues gain an extra one at level 10.
At each ASI milestone, the player faces a binary choice:
Some feats carry prerequisites — requirements a character must already meet before selection is legal. The Polearm Master feat, for instance, has no prerequisite, making it available at level 4. Heavily Armored requires proficiency with medium armor, which gates it away from characters like Wizards unless they've already taken Lightly Armored and Moderately Armored in sequence.
A handful of feats — Alert, Lucky, and Tough among them — are effectively prereq-free and sit in a category of universally accessible options that work for nearly any build.
The how it works page goes deeper into the level-by-level structure of character advancement if the ASI timing is unfamiliar territory.
Common scenarios
Feat selection tends to cluster around three broad functional goals:
Combat optimization — Feats like Great Weapon Master, Sharpshooter, and Crossbow Expert are famous (occasionally infamous) for the raw damage ceiling they unlock. Great Weapon Master's -5 attack / +10 damage toggle, for example, interacts directly with Bless and advantage sources in ways that experienced players plan around from level 1.
Spellcasting expansion — War Caster and Spell Sniper allow spellcasters to maintain concentration more reliably or extend attack-spell range. Magic Initiate lets a non-spellcaster access two cantrips and one 1st-level spell from any class list, opening Warlock's Eldritch Blast to a Fighter or Find Familiar to a Rogue.
Utility and survivability — Lucky grants 3 luck points per long rest that can reroll any attack roll, ability check, or saving throw — one of the statistically strongest general-purpose feats in the game. Alert adds +5 to initiative and prevents surprise, which at high-stakes tables can functionally determine whether a character survives an ambush.

Decision boundaries
The feat-versus-ASI decision is rarely obvious, and the right answer depends on two variables: where the ability score currently sits, and what the feat actually does at that character's level.
A Strength-based Fighter at 17 Strength faces a meaningful fork. Taking the standard ASI to reach 18 Strength increases the attack and damage bonus by +1 — a small but consistent gain across every attack forever. Taking Great Weapon Master instead unlocks conditional +10 damage that, on a Fighter with Action Surge and multiple attacks, can dwarf any +1 bonus in a single round. The math favors Great Weapon Master substantially once attack rolls are reliable.
Contrast that with a Cleric at 15 Wisdom. Wisdom 15 means the character's spell save DC and spell attack bonus are both one point behind their potential. Taking a combat feat here delays that correction, and for a primary caster, that gap shows up on every encounter. Most optimization frameworks — including those discussed in the D&D community resource Treantmonk's Guide to Wizards — recommend reaching 20 in a primary casting stat before heavily investing in feats.
The other decision boundary involves party role. A tank character choosing between Sentinel (which stops enemies from disengaging and enables opportunity attacks on movement) and a raw Constitution increase is weighing control utility against durability. Both matter — but Sentinel's value scales with how often enemies try to move past the character, which depends entirely on the dungeon master's encounter design. Feats with conditional triggers are always a mild bet on how the table actually plays.
