In Dungeons & Dragons, a coup de grace is a decisive finishing move used when an enemy is helpless. This rule helps resolve situations where a creature is unconscious, paralyzed, or otherwise unable to defend itself, and another character chooses to deliver a lethal blow. The coup de grace is not an automatic kill; instead, it is a targeted attack that automatically succeeds against a helpless foe and resolves using the attacker’s normal damage rolls. Used responsibly, it supports adjudication at the table by clarifying how lethal attacks work against helpless opponents within the framework of death saves, incapacitation, and action economy.
What Is a Coup de Grace in D&D?
A coup de grace is a specific application of the rules for attacking helpless creatures in D&D. It represents a focused, unavoidable strike delivered to a foe that cannot reasonably defend itself. While the term originates from real-world French military usage, its role in D&D is mechanically precise: it allows a character to automatically hit a helpless target and deal normal damage. The intent is to give a clear answer for narratively justified executions or mercy kills while remaining consistent with the dice-based resolution that defines the game. Unlike spells such as sleep or effects that impose disadvantage, the coup de grace is a targeted physical action that reflects intent and opportunity rather than a magical override.
When Can You Use a Coup de Grace?
Conditions That Make a Creature Helpless
A creature must be helpless for a coup de grace to apply. Common conditions that create this state include being unconscious, paralyzed, grappled in a way that restricts movement, restrained, or stunned. In each case, the creature is aware of what is happening but cannot act to avoid or defend against the attack. The Dungeon Master has the final say on whether a specific situation qualifies, but general guidance is that the target must be incapable of moving, acting, or defending itself. This typically means the creature is not resistant or immune to the chosen method of attack, as the focus is on helplessness rather than vulnerability or resistance.
Actions Required to Deliver a Coup de Grace
Delivering a coup de grace requires an action from the attacker. Some tables allow it as part of an attack action when multiple attacks are permitted, while others treat it as its own dedicated action to preserve action economy. Because it targets a helpless foe, it does not require the attacker to make an attack roll; instead, the attack automatically hits. The attacker still adds their normal modifiers to damage and rolls the appropriate dice for the weapon or natural attack used. This makes the coup de grace efficient from a resolution standpoint but still meaningful because it ties into the attacker’s core offensive stats, such as their proficiency bonus and relevant ability modifiers.
How Coup de Grace Interacts With Death Saves
Automatic Failure on Death Saves
A helpless creature making death saves is already in a precarious state. Under the standard rules, such a creature has disadvantage on death saving throws. When a coup de grace is used against a creature that is currently rolling death saves, the attack bypasses those saves entirely and deals damage normally. If the damage reduces the creature to 0 hit points or lower, the creature dies. In practice, this means that a coup de grace is one of the few things that can end a helpless creature’s life immediately, regardless of how close that creature might be to stabilizing. This functions within the existing death save framework but operates as a distinct, conditional finishing move rather than a spell or effect that automatically triggers a death save outcome.
Stabilization and Healing Considerations
Because a coup de grace ignores death saves, it also bypasses the stabilizing effects that normally keep a dying creature alive. A character who receives healing or succeeds on a death save without receiving damage remains at 0 hit points until stabilized by a spell like cure wounds or similar means. Because the coup de grace inflicts damage directly, it prevents healing from taking effect mid-resolution in most interpretations. This reinforces the finality of the action while remaining consistent with the idea that healing magic requires time, concentration, or specific conditions to take effect. DMs may choose to narrate this as the damage occurring before stabilizing magic can be completed or applied.
Official Rules Reference and Common Variants
The core rule guidance on coup de grace appears in the Player’s Handbook under combat rules for helpless creatures and optional rules in the Dungeon Master’s Guide. In the basic rules, a helpless creature can be attacked with advantage and is automatically hit if the attacker chooses to deliver a coup de grace. Some tables choose to houserule the action economy so that a coup de grace is part of the Attack action rather than a separate action, or they allow it when using certain weapons or fighting styles. Others restrict when or how often it can be used to avoid it feeling mandatory in every encounter with a downed enemy. These decisions reflect table preferences rather than strict RAW, but the official guidance supports a consistent default that makes the rule predictable and reliable.
Practical Examples and Tactical Use
- A rogue using a shortsword can deliver a coup de grace to an unconscious enemy, automatically hitting and rolling damage normally without needing to roll to hit.
- A fighter grappling a paralyzed opponent can choose to use an action to finish the helpless creature, dealing normal damage with their weapon instead of making another attack roll.
- A monster’s lair ability or specific creature trait may describe a “mercy strike” or finishing behavior; in these cases, DMs can flavor a coup de grace as part of the monster’s capabilities if it fits the design.
- In social or narrative contexts, DMs may allow a coup de grace to represent a decisive, story-driven killing blow, provided it aligns with the fiction and does not bypass intended consequences.
Common Misunderstandings and FAQs
Because the rule is simple in principle but powerful in practice, several questions come up at many tables. Below are concise answers to some of the most frequent points of confusion, keeping to the RAW expectations while leaving room for DM judgment.
Do you roll to hit when delivering a coup de grace?
No. Because the target is helpless, the attack automatically hits. You still add your normal damage modifiers and roll the weapon’s damage dice as normal, but there is no attack roll required.
Can a coup de grace be used on a willing target?
While unusual, a willing target could be considered helpless if they choose not to defend themselves. In such cases, DMs may allow a coup de grace, but most will require clear consent and narrative justification before applying the rule.
Does a coup de grace trigger reactions like opportunity attacks?
No. Opportunity attacks are provoked by movement, not by a standard action like a melee or ranged attack, so delivering a coup de grace does not trigger them. Specific creature reactions or features that trigger on being attacked may still apply if the DM rules they are relevant.
Can a coup de grace be resisted, negated, or modified?
Because the attack automatically hits, effects that normally cause a miss, such as shield or the disengage action, do not apply. However, effects that modify damage before it is dealt, such as resistance, immunity, or damage reduction, still apply normally. This means a resistance to slashing damage, for example, would reduce the damage of a coup de grace if used with a slashing weapon.
