DnD Stealth and Hiding Rules

Stealth and hiding mechanics govern how characters in Dungeons & Dragons conceal their presence from enemies, move undetected through dangerous spaces, and gain tactical advantages through concealment. These rules intersect with Dexterity checks, the Hide action, passive Perception scores, and the conditions that permit or prohibit attempted concealment. Disputes at the table most often arise from ambiguity in the 5th Edition rules around exactly when a character can hide and what breaks that hidden state — making precision in applying these mechanics critical to consistent play.

Definition and scope

In 5th Edition D&D, stealth is governed primarily by the Dexterity (Stealth) skill, which is described in the Player's Handbook and the D&D Basic Rules. The skill covers moving silently, concealing oneself, and avoiding detection through sound or sight.

The Hidden condition is not a formally named condition in the 5th Edition conditions list (see DnD Conditions Reference), but it is a recognized game state with specific mechanical consequences: a hidden creature has advantage on attack rolls against creatures that cannot see it, and those creatures have disadvantage on attack rolls against the hidden creature.

The scope of stealth rules extends across three pillars of play:

• Combat — hiding as a tactical action to gain positional advantage
• Exploration — moving through areas without triggering encounters
• Social encounters — surveillance, eavesdropping, and infiltration scenarios

The full framework for these pillars is described in the DnD Exploration Rules and DnD Social Interaction Rules sections of this reference.

How it works

The Hide Action

During combat, a character can use the Hide action (a standard action, per DnD Action Types Explained) to attempt to conceal themselves. The character makes a Dexterity (Stealth) check, and the result is compared against the passive Perception scores of nearby creatures — or against active Wisdom (Perception) checks if those creatures are actively searching.

The passive Perception score equals 10 + the creature's Wisdom modifier + any Perception proficiency bonus. A character with a Wisdom score of 14 (+2 modifier) and proficiency in Perception (assuming +3 proficiency bonus at typical adventuring levels) holds a passive Perception of 15.

Preconditions for hiding

The 5th Edition rules, as clarified in the Dungeon Master's Guide and D&D Beyond Rules Compendium, establish that a character must be obscured from view to attempt the Hide action. This means:

1. The character must be in a lightly or heavily obscured area (dim light, fog, foliage, etc.) — or behind total cover from all observing creatures.
2. The character must not be directly observed at the moment the Hide action is attempted.
3. No condition on the character (such as the Blinded condition being irrelevant — it is the observer's ability to see that matters) prevents the attempt.

Breaking the hidden state

A hidden character loses the Hidden state when any of the following occur:

1. The character makes an attack roll.
2. The character casts a spell with a visible effect.
3. The character moves into a space that is not obscured from an observer.
4. An observer succeeds on a Wisdom (Perception) check against the character's Stealth check result.
5. The character takes an action that creates substantial noise or visible disturbance.

DnD Light and Vision Rules directly inform when a location is considered obscured, making those rules inseparable from stealth adjudication.

Common scenarios

Ambush setup: A Rogue uses the Hide action at the start of combat after breaking line of sight. If the Stealth check result exceeds the target's passive Perception, the Rogue attacks with advantage on the first strike — a core component of the Sneak Attack feature.

Scouting ahead: During exploration, the entire party may attempt a group Dexterity (Stealth) check when moving through an area patrolled by enemies. Per the D&D Basic Rules, a group check succeeds if at least half the group succeeds — meaning 3 out of 5 characters need to pass for the party to avoid detection.

Hiding mid-combat (the "Skulker" scenario): The Skulker feat (from the Player's Handbook) allows a character to attempt to hide when only lightly obscured from the creature they are hiding from. Without that feat, only heavy obscurement or total cover qualifies, which significantly narrows options in open combat environments.

Invisible characters: Invisibility does not automatically confer the Hidden state, but it does impose disadvantage on Perception checks to detect the invisible creature. The interaction between the DnD Conditions Reference entries for Invisible and the Stealth system is a distinct and frequently adjudicated overlap. See also DnD Cover Rules for how physical obstacles interact with line-of-sight requirements.

Decision boundaries

The stealth system requires Dungeon Masters to make judgment calls at 4 specific decision points:

1. Is the character sufficiently obscured to attempt hiding? — This is the most contested ruling. The DM determines whether the available cover or obscurement meets the threshold, a judgment described in the Dungeon Master's authority framework at DnD Dungeon Master Rules and discussed in context at How DnD Works: Conceptual Overview.

2. What Perception score applies? — Passive versus active Perception. Creatures that are already alert or actively searching use active checks; unaware creatures use passive scores.

3. Does moving break the hidden state? — Movement through a continuously obscured area (a dark corridor, dense forest) does not necessarily break concealment. Movement into a lit or open space does. The DnD Movement and Positioning Rules provide the spatial context for this ruling.

4. When does attacking reveal position? — Attacking breaks the hidden state, but the attack itself still benefits from advantage because both the hidden state and the attack resolve simultaneously. After the attack, the attacker's position is revealed.

Contrast — Stealth check vs. Passive Perception vs. Active Perception:

These distinctions align with the broader skill resolution framework described in DnD Skills and Proficiencies and the DnD Difficulty Class Rules that govern when the DM sets static DCs versus calling for opposed checks.
