Dungeons & Dragons 5th Edition treats stealth as a core interaction between a creature trying to avoid detection and others trying to notice it. At its simplest, a creature attempts to hide by moving quietly, concealing itself, and avoiding line of sight, while observers make Perception checks to detect it. This article explains how the stealth mechanic works in 5e, what the rules state and do not state, how to determine when hiding is possible, common conditions that affect stealth, and practical tips for players and Dungeon Masters. Topics include the hiding rules, the stealth versus perception contest, cover and concealment, movement and noise, and how to adjudicate stealth in different environments.
How Hiding Works in 5e
The rules for hiding appear in the Player's Handbook and are summarized in the Dungeon Master's Guide and Monster Manual. A creature can hide when it is unseen and otherwise obscured from observers. The most common way to determine success is a Dexterity (Stealth) check opposed by a Wisdom (Perception) check. The hiding creature attempts to avoid detection, while the observer attempts to notice it. The outcome depends on comparative skill, circumstances, and whether the creature has any reason to believe the hidden creature could be present.
Making a Hide Check
When you take the Hide action, you make a Dexterity (Stealth) check. The DM then decides whether any creatures are actively searching for hidden foes. If creatures are not actively searching, they might not make Perception checks at all. If a creature is searching, it usually makes a Wisdom (Perception) check. The DM compares the two results to determine whether you successfully hide. This can be treated as an opposed check, or the DM can simply decide whether, given the situation, noticing the hidden character is reasonable.
When You Can Hide
The general guidance is that you can hide when you are unseen and have some form of cover or concealment. Cover provides physical protection that may also obscure you, while concealment provides visual obscurity. The DM determines whether a given environment allows hiding based on line of sight, lighting, and ambient noise. In dim light or darkness, hiding is often easier, though creatures with darkvision may still perceive you. Total cover prevents you from being targeted, but it usually also prevents you from observing the area unless you have a way to see through the cover. Partial cover or half cover can make it harder to hit you while still allowing you a hiding attempt if the DM determines you are effectively obscured.
Opposed Checks and Passive Perception
Opposed Check Approach
In an opposed check framework, the creature attempting to hide makes a Dexterity (Stealth) check and the creature searching makes a Wisdom (Perception) check. The higher result determines success. A tie typically means the searcher notices something amiss, but may not pinpoint the exact location of the hidden creature. The DM may also apply advantage or disadvantage to either check based on circumstances, such as the searcher being distracted or the hidden character making noise.
Passive Perception in Hidden Situations
Many groups opt not to use opposed checks and instead rely on Passive Perception. In this approach, the DM sets a Difficulty Class based on the environment and the hidden creature's behavior. The searcher's Passive Perception is then compared to the DC. If the DC exceeds the searcher's Passive Perception, the hidden creature remains undetected. This can speed up play and reduce constant die rolls while still reflecting the likelihood of detection based on cover, noise, and awareness. The DM may adjust the DC for factors such as careful observation, favorable terrain, or the hidden creature's unusual behavior.
Conditions That Affect Stealth
Several game features and conditions influence stealth. Invisibility, for example, grants a significant advantage while hiding, though attacking or casting certain spells can reveal your position. Observers may still detect an invisible creature through sound, interaction with objects, or other sensory clues. Environments with loud water, crackling fire, or howling wind can impose penalties on Stealth checks or increase the DC for hiding. Conversely, environmental features like foliage, shadows, or urban clutter can provide bonuses to Stealth by obscuring your outline. Movement generally imposes penalties to hiding, since motion draws attention, but the rules allow a creature to hide even while moving if the distance is short and the check is successful.
| Condition | Effect on Stealth | Notes |
|---|---|---|
| Invisibility | Makes hiding easier, but can be detected by sound or other means | Certain spells and attacks may reveal your position |
| Cover or Half Cover | Often improves chances to hide | DM adjudicates whether it provides effective obscurity |
| Loud Environment (water, fire, wind) | Harder to hide; may increase DC | Noise can travel and mask subtler sounds |
| Darkness or Dim Light | Generally improves hiding chances | Darkvision can partially offset concealment |
| Active Search | More likely to prompt Perception checks | Searchers are alert and methodical |
| Passive Observation | Less likely to provoke checks | Success depends on DC and Passive Perception |
Practical Tips for Players
As a player, stealth is improved by choosing your position carefully, moving quietly, and using environmental features. Before attempting to hide, ask the DM about lighting, cover, and noise level. If you are in bright daylight in an open field, hiding is likely to be difficult. In a shadowy alley with barrels and crates, you may have a good chance. Use your Dexterity modifier to your advantage, and consider class features, spells, or items that enhance stealth. The Hide action can be combined with movement as part of your move, provided the movement does not violate the conditions for hiding. Communication with your DM about your intent and the environment helps ensure consistent rulings.
Positioning and Patience
Position yourself so that you have reliable cover or concealment and avoid line of sight. Minimize noise by avoiding running, climbing, or interacting with loose objects. Be aware of creatures with keen senses or passive Perception; some enemies automatically detect hidden characters as part of their traits. Patience pays off: sometimes waiting to move until observers are less vigilant results in better outcomes. Remember that hiding does not grant total immunity, only a reduced chance to be seen, heard, or pinpointed.
Practical Tips for DMs
As a DM, stealth should feel meaningful but not punitive. Describe the environment in terms that help players make informed choices about cover, noise, and visibility. Use passive Perception scores to streamline play while still reflecting how observant creatures are. Adjust DCs based on conditions, such as weather, lighting, and the quality of cover. When in doubt, require an active search to detect hidden characters rather than assuming automatic success. Reward creative use of the environment and give players clear feedback about why a hiding attempt succeeds or fails. Maintain consistency so players can learn how the world reacts to their actions.
Creature Awareness and Senses
Consider the creature's sensory capabilities. A creature with blindsight may ignore visual concealment, while tremorsense or scent may bypass typical hiding strategies. High passive Perception makes a character more likely to notice subtle disturbances. In a wilderness setting, describe distant cracking branches or soft footprints that may reveal a hidden figure even without a roll. In urban settings, ambient noise can mask quiet movements, while torchlight or streetlight can expose silhouettes. Use the environment to make stealth tense and dynamic.
