What’s the difference between Spiritual Weapon and Mordenkainen’s Sword? At their core, both are spells that create a magical weapon to attack enemies, but they differ significantly in several key aspects. Spiritual Weapon, a 2nd-level conjuration spell, is cast as a bonus action, summons a spectral weapon, and scales well with higher spellcasting modifiers. It deals force damage and can be repositioned each turn with a bonus action. Mordenkainen’s Sword, a 7th-level evocation spell, requires an action to cast, summons a sword that deals more damage, especially on a critical hit, and can also be moved with a bonus action. In short, Spiritual Weapon offers action economy and scaling, while Mordenkainen’s Sword provides raw power at a higher spell slot cost.
Diving Deeper: Key Differences
While the immediate difference is action economy (bonus action vs. action), a more nuanced comparison reveals significant tactical and strategic implications.
Casting Time & Action Economy
- Spiritual Weapon: This is a game-changer. Casting as a bonus action means you can still use your action to attack, cast another spell (a cantrip), or take other actions. This flexibility makes it highly valuable, especially at lower levels.
- Mordenkainen’s Sword: Requiring an action to cast significantly limits your options on the turn you summon it. This makes it a more situational choice, best used when you can afford to sacrifice your action for the potential damage output.
Damage & Scaling
- Spiritual Weapon: Deals 1d8 force damage + your spellcasting ability modifier. This scaling means that as your spellcasting ability increases, so does the damage output, making it a reliable source of consistent damage.
- Mordenkainen’s Sword: Deals 3d10 force damage. This raw damage is higher than Spiritual Weapon at base, and the potential for a high damage critical hit is also much higher. However, its damage does not inherently scale with your spellcasting modifier beyond the initial cast.
Spell Level & Resource Cost
- Spiritual Weapon: As a 2nd-level spell, it’s accessible earlier in the game and less taxing on your spell slots. This makes it a sustainable option for consistent damage output.
- Mordenkainen’s Sword: A 7th-level spell, this is a significant resource investment. It should be used strategically, considering the opportunity cost of potentially casting other powerful spells.
Range & Movement
- Spiritual Weapon: The weapon appears within 60 feet of you and can be moved up to 20 feet each turn with a bonus action.
- Mordenkainen’s Sword: The weapon appears within 60 feet of you and can be moved up to 20 feet each turn with a bonus action.
Target Selection
- Spiritual Weapon: Allows you to make a melee spell attack against a creature within 5 feet of the weapon.
- Mordenkainen’s Sword: Allows you to attack a creature within 5 feet of the sword, making it similar to spiritual weapon in this way.
Duration & Concentration
- Spiritual Weapon: Lasts for 1 minute and does not require concentration. This means you can maintain the weapon while casting other concentration spells or taking damage.
- Mordenkainen’s Sword: Lasts for up to 1 minute and requires concentration. This is a huge downside! Losing concentration ends the spell immediately, wasting a precious 7th-level spell slot.
Strategic Considerations
The choice between Spiritual Weapon and Mordenkainen’s Sword boils down to your playstyle, party composition, and the specific encounter. Spiritual Weapon shines in scenarios where action economy and consistent damage are crucial, while Mordenkainen’s Sword offers burst potential in situations where a high-damage output is needed quickly.
Think of Spiritual Weapon as a reliable sidearm, always ready for action and costing little to use. Mordenkainen’s Sword, on the other hand, is a heavy artillery piece, powerful but expensive and requiring careful deployment.
Frequently Asked Questions (FAQs)
Here are some common questions regarding these two powerful spells:
H3 Can you cast Spiritual Weapon and another spell in the same turn?
Yes, but with limitations. You can cast Spiritual Weapon (as a bonus action) and then cast a cantrip (as an action) in the same turn. However, you cannot cast two spells of 1st level or higher in the same turn.
H3 Can Spiritual Weapon move out of range?
If the weapon goes beyond the 60-foot spell range, it will return to you and hover. Each round after the first, you can use a bonus action to redirect the weapon to a new target, and if you do not the weapon will attack the previous round’s target.
H3 Can you occupy the same space as a Spiritual Weapon?
Yes. Spiritual Weapon does not occupy a square in the same way a creature does. It’s a spell effect, not a physical obstruction.
H3 Does Spiritual Weapon get 2 attacks?
No. You can only make one attack with Spiritual Weapon per turn, using your bonus action.
H3 Can an enemy walk through a Spiritual Weapon?
Yes. Since Spiritual Weapon doesn’t create difficult terrain or act as an obstacle, creatures can move through its space without penalty.
H3 Can you use Booming Blade on Spiritual Weapon?
No. Booming Blade requires a melee weapon attack with a weapon. Since the Spiritual Weapon is not a weapon, it is not a valid target for the Booming Blade spell.
H3 Can you touch a Spiritual Weapon?
While you could potentially interact with the space the weapon occupies, it isn’t a tangible object you can physically grasp and wield. It’s a magical manifestation controlled by your spellcasting.
H3 Is Spiritual Weapon magic?
Absolutely. It is a spell, it uses your spell attack modifier for each attack, and it deals force damage which is considered almost always magical.
H3 Does Spiritual Weapon stay up if you go unconscious?
Yes, because Spiritual Weapon does not require concentration, it will continue to exist for its full duration even if you become unconscious. However, you will not be able to use your bonus action to attack with it while unconscious.
H3 Can Spiritual Weapon travel through walls?
No. Despite being spectral, Spiritual Weapon is blocked by physical barriers like walls.
H3 Does Spiritual Weapon end if you go unconscious?
No. Spiritual Weapon doesn’t require concentration, so its duration persists even if you fall unconscious or even die.
H3 Do you need line of sight for Spiritual Weapon?
No. You need to be able to see the space you cast it into and to move the weapon each turn, but you do not need line of sight to the target.
H3 What action does Spiritual Weapon take to cast?
Spiritual Weapon requires a bonus action to cast and allows you to make an attack with it on the turn it is cast.

This combination of detailed explanation and FAQs should provide a comprehensive understanding of the differences between these two iconic spells.
