Disarming an opponent in Dungeons & Dragons 5e is a tactical choice that trades offense for control, often turning the tide of combat by removing a weapon or forcing a risky reacquisition. This guide explains how the disarm action works in the Player’s Handbook and Dungeon Master’s Guide, when it is reasonable to attempt one, and how optional rules from Xanathar’s Guide to Everything and Tasha’s Cauldron of Everything reshape its utility. Whether you are a player deciding when to Strike or a Dungeon Master adjudicating attempts, you will find lasting principles for using disarm that apply across editions and campaigns.
What Is a Disarm in D&D 5e
A disarm is an attempt to knock a creature’s weapon or item from its grasp, typically through a melee weapon attack. While the core rules do not give disarm a dedicated action option, the rules for the Attack action and opportunity attacks, plus the general ability contest framework, allow a DM to call for an attack roll contest or an Athletics check contest. The attack gains the normal modifiers of your fighting style, class features, and any applicable bonuses or penalties. The target’s ability to hold on depends on Strength, size of the object, and whether the target is willing or resistant to being disarmed. Because disarm is a contested interaction, success is never automatic, and risk and reward are baked into the attempt.
When You Can Attempt to Disarm
You can attempt to disarm when you make a melee weapon attack against a creature that is holding or wearing an item you want to remove. Common situations include grappling a weapon-wielding enemy, interacting during a parley, or using the Attack action on an exposed object. The DM decides whether the object can reasonably be affected; dedicated weapons and shields are common targets, while improvised tools or loosely held objects may be easier to knock away. Certain spells and class features, such as the Grappler feat or effects that impose grappled or restrained conditions, can create more favorable circumstances for a disarm. The key requirement is that the target is within reach and the item is accessible, and the DM judges that the attempt is feasible under the fiction.
Standard Approach in 5e
Most groups use one of two approaches from the official rules:
- Attack roll contest: The attacker makes a weapon attack and the target makes a Strength (Athletics) check or a weapon attack to maintain hold. The higher result wins.
- Athletics check contest: The attacker makes an Athletics check to knock the item free, opposed by the target’s Athletics check.
Danger: if the attacker rolls poorly, the DM may rule that the attacker leaves an opening, granting advantage to the target on its next opportunity attack or reaction. This preserves tension and prevents reckless disarm spamming.
Optional Rules and Alternatives
Xanathar’s Guide to Everything and Tasha’s Cauldorn of Everything expand the toolkit for disarming items or snatching objects. The optional disarm rule from XGTE uses an opposed Athletics check instead of an attack roll, making Strength and size more central. Tasha’s introduces the concept of using the Attack action to interact with an object, such as knocking an item from a creature’s hand, trading attack bonus for control. The Grappler feat further incentivizes disarm-focused builds by letting you move a grappled creature and attempt to unbalance them. These options give DMs ways to tune how often and how decisive disarms should be in their table.
Mechanical Effects and Consequences
The immediate effect of a successful disarm is that the target no longer has that weapon or item in its grasp; the object lands in an unoccupied space within 5 feet, unless another outcome is specified. Many DMs rule that the target can use its reaction to attempt to catch the item, often with a Dexterity (Sleight of Hand) check versus the attacker’s Athletics check. If the reaction fails, the item may be knocked farther away or into a different zone, potentially into environmental hazards. On the grid, moving to retrieve a dropped weapon usually costs movement, and doing so while prone, grappled, or otherwise constrained can be difficult or impossible. Because the target typically gets no chance to react until after the check, disarm creates a clear tempo swing: you disrupt an enemy’s action and force them to spend resources to recover it.
Example Outcomes After a Successful Disarm
| Object | Verified Detail | Source Type |
|---|---|---|
| Weapon | Dropped in an unoccupied space within 5 feet of the target; target may use reaction to attempt catch. | PHB & XGTE optional rules |
| Shield | Functions as a weapon for disarm purposes; dropping shield grants target disadvantage on AC until they regain it. | PHB interactions |
| Held item (torch, potion, tool) | Same drop rules, often easier to knock away due to lesser Combat relevance. | DM adjudication |
| Two-handed weapon | Disarming a two-handed weapon often leaves the target unarmed unless they have another weapon or can draw one quickly. | Practical play |
| Mounted combat | Target on a mount may drop item to the ground; dismount effects handled separately by DM. | Optional guidance |
Tactical Considerations for Players
For players, disarm is a trade-off: you give up damage potential to gain battlefield control. It shines when an enemy’s weapon is dramatically better than yours, when they rely on a single powerful item, or when you need to create an opening for allies. Classes with high Strength, Athletics proficiency, or reach weapons tend to succeed more often at disarming. Fighters with the Dueling fighting style or monks focusing on disarms can make the tactic part of a coherent identity. Always consider the cost: if your attack misses or the contested check fails, you may give the enemy an opportunity to strike back. Using Help actions to set up a disarm, combining it with grapples, or coordinating with spells that impose disadvantage can improve your odds.
Design and Dungeon Master Guidance
For DMs, disarm is a tool for pacing and drama rather than a default tactic. Decide how frequently you want items to change hands: liberal use encourages risk-taking and flashy moments, while conservative use preserves the integrity of signature weapons. Use creature abilities to reflect narrative control; a villain who never drops their sword reinforces their menace, whereas a rival who intentionally disarms can show skill or mercy. Adjust DCs, hit bonuses, and contested checks to match the table’s lethality and style. If you use optional rules, communicate them at session zero so players understand when and how to attempt disarms. Remember that combat is about objectives, not just hit points; disarm can serve goals like capturing foes, denying access to relics, or forcing moral choices about lethal force.
Common Misconceptions and Edge Cases
Because disarm is not a named action in the Player’s Handbook, many groups misunderstand its baseline rules. You do not spend an extra action to disarm; you replace one attack with an attempt to knock something free. You cannot typically disarm a willing creature without their cooperation, and magical or incorporeal weapons are usually subject to DM discretion. Some magic items and class features impose advantage or penalties to disarm attempts; these should be applied consistently. Reach weapons allow you to threaten a disarm from a safer distance, but opportunity attacks may still trigger if you leave a creature’s reach. Objects such as potions or loose gear are often easier to knock away than a character’s bonded sword, and the DM is the final arbiter of what can reasonably be targeted. These nuances keep disarm interesting and fair across different builds and situations.
