Conditions in D&D: Rules Reference
Conditions are one of the most mechanically consequential systems in Dungeons & Dragons — the difference between a fighter who acts normally and one who can't stand up, see, or react is often a single saving throw. This page covers all 15 official conditions defined in the 5th Edition Player's Handbook and Dungeon Master's Guide, how they interact with core mechanics, and where the rules draw hard lines that frequently surprise newer players. Whether a character is navigating a complex encounter or just trying to understand why the grappled condition doesn't do what they thought it did, the rules here reward close reading.
Definition and scope
A condition is a defined game state that modifies what a creature can do — or what can be done to it — for as long as the condition persists. The 5th Edition rules list exactly 15 conditions (Player's Handbook, Appendix A):
Each condition has a discrete mechanical definition. Conditions do not stack with themselves — a creature either is or isn't charmed, for instance. The exception is Exhaustion, which has 6 severity levels that stack cumulatively. A creature at Exhaustion level 3 has disadvantage on ability checks, halved speed, and disadvantage on attack rolls and saving throws simultaneously.
Conditions are imposed by spells, monster abilities, environmental hazards, and class features. They end when the triggering effect says they end — which might be a duration, a saving throw on a subsequent turn, a specific action, or a flat-out narrative event like being cured by lesser restoration.
How it works
Mechanically, conditions either restrict actions, impose disadvantage or advantage, or modify how the creature interacts with attack rolls. The Blinded condition, for example, causes the afflicted creature to automatically fail any check requiring sight, grants disadvantage on its attack rolls, and grants advantage to attack rolls made against it — three distinct mechanical effects bundled into one named state.
Several conditions carry embedded sub-conditions. Paralyzed includes the Incapacitated condition within it, meaning a paralyzed creature also cannot take actions or reactions. Unconscious includes both Incapacitated and Prone. This layering matters for spell targeting, class features, and abilities that trigger specifically off one of the sub-conditions.
Grappled is frequently misread. It reduces a creature's speed to 0 — that's the entire mechanical effect. It does not impose disadvantage on attack rolls, and it does not prevent the grappled creature from taking any action other than moving. A grappled wizard can still cast fireball at full effectiveness, which surprises a lot of players at the table.
Prone is the condition with the most spatial nuance. A prone creature grants advantage to melee attack rolls made against it but imposes disadvantage on ranged attacks targeting it. Crawling (the only horizontal movement available while prone) costs 1 extra foot of movement per foot traveled. Standing up costs half a creature's total movement speed — not half its remaining movement.
The key dimensions of D&D mechanics include action economy, and conditions interact with that economy in asymmetric ways. Stunned, for instance, incapacitates a creature, fails it on Strength and Dexterity saving throws automatically, and grants advantage to all attack rolls against it — effectively removing a creature from combat participation while making it a free-damage target.
Common scenarios
Paralyzed is the condition most associated with automatic critical hits. Any attack that hits a paralyzed creature within 5 feet is a critical hit — not just an attack with advantage, but an actual crit that doubles dice. This makes paralysis disproportionately dangerous against creatures with large hit dice, and it's why Hold Person and Hold Monster are among the most feared concentration spells in the game.
Frightened comes with two effects that players sometimes conflate: disadvantage on ability checks and attack rolls while the source of fear is in line of sight, and a hard prohibition on moving closer to the source. The second effect is directional — a frightened creature can still move laterally or away; it simply cannot voluntarily move toward the thing it fears.
Exhaustion appears most often in wilderness survival scenarios and certain class abilities. The D&D FAQ addresses several edge cases around exhaustion removal — notably, a long rest removes only 1 level of exhaustion, meaning a character at level 5 exhaustion (speed of 0, disadvantage on all attack rolls, saving throws, and ability checks) needs 5 consecutive long rests to fully recover.
Decision boundaries
The sharpest rules boundary in the conditions system involves immunity versus resistance. Conditions do not have resistance — a creature either is immune to a condition or is subject to it. There is no "partial frightened." This matters when magical effects attempt to impose conditions on creatures with immunity, such as using Hold Person on an undead creature (which has immunity to the Paralyzed and Frightened conditions under most stat blocks).
Concentration also creates a critical decision boundary. Many condition-imposing spells require concentration, meaning a caster maintaining Hypnotic Pattern (which imposes the Incapacitated condition) can lose it the moment they take damage and fail a Constitution saving throw (DC 10 or half the damage taken, whichever is higher). This is why Warcasters and War Clerics invest heavily in Constitution saving throw proficiency — it's the single mechanical protection for the most powerful condition-imposing spells in the game.
Conditions imposed by non-spell means — monster abilities like a dragon's Frightful Presence or environmental effects — follow the same rules but are often tied to different removal triggers, sometimes requiring no action at all but simply moving beyond a certain range or waiting for a duration to expire. For a broader orientation to how these rules fit together, the D&D rules overview provides the foundational framework.
