Disintegrate vs. Forcecage: A Deep Dive into D&D’s Magical Arsenal

Disintegrate and Forcecage are powerful spells in Dungeons & Dragons, but they are absolutely not the same. Disintegrate is an offensive spell that deals massive damage and can instantly destroy certain objects and constructs, while Forcecage is a defensive spell that creates an immobile prison of magical force. Their only real connection is that Disintegrate can be used as a counter to Forcecage. They have completely different purposes, mechanisms, and effects. One is a hammer, the other is a cage.

Understanding the Spells

To fully grasp the difference, let’s examine each spell individually:

Disintegrate

This spell is a 6th-level Transmutation spell. Its primary function is dealing massive force damage. If this damage reduces a creature to 0 hit points, it is disintegrated, turning into a pile of fine dust. More importantly, it has a specific clause: “The beam magically disintegrates a Large or smaller nonmagical object or a creation of magical force.” This is the key to its interaction with spells like Wall of Force and, crucially, Forcecage. The damage type is Arcane.

Forcecage

This spell is a 7th-level Conjuration spell. It conjures an immobile, invisible, cube-shaped prison made of magical force. You can choose to create a cage with bars or a solid box. The prison prevents nonmagical egress and makes magical egress difficult, requiring a Charisma saving throw. Importantly, the spell description states that it “can’t be dispelled by dispel magic.” However, as we know from the Disintegrate description, that does not mean it is invulnerable. The spell creates the prison, and the prison lasts for one hour.

The Critical Difference: Interaction and Vulnerability

The crucial point is the vulnerability of Forcecage to Disintegrate. While Forcecage is immune to Dispel Magic, it is specifically vulnerable to the effect of a Disintegrate spell. Since it is “a creation of magical force,” it can be instantly destroyed by the Disintegrate spell. Wall of Force operates under the same principle. This vulnerability creates a strategic dynamic in the game. It is also worth noting that Forcecage consumes 1,500 gp worth of ruby dust.

Strategic Implications

The interaction between these spells creates interesting strategic dynamics:

• Counterplay: A caster trapped in a Forcecage by an enemy caster would reasonably have Disintegrate as their first option to escape.
• Spell Selection: Knowing that Forcecage is vulnerable to Disintegrate might influence a caster’s spell selection and strategic planning.
• DM Considerations: DMs can use this interaction to create challenging encounters, requiring players to think creatively about their spell usage.

Frequently Asked Questions (FAQs)

Here are some frequently asked questions to further clarify the relationship between Disintegrate and Forcecage:

1. Can Disintegrate be used to destroy other creations of magical force besides Forcecage?

Yes. Disintegrate can destroy any “creation of magical force,” as long as it’s Large or smaller. This includes the Wall of Force spell and, depending on the DM’s interpretation, certain constructs or objects created through other spells.

2. Does Forcecage block Disintegrate?

No. While Forcecage blocks most spells and physical attacks from passing through, it doesn’t prevent a Disintegrate spell from targeting and destroying the Forcecage itself.

3. If a creature is inside a Forcecage, can they be targeted by Disintegrate?

Yes, the creature inside can be targeted by Disintegrate. The Forcecage does not provide total cover. If the creature is reduced to 0 hit points by the spell, they are disintegrated.

4. Does Disintegrate work on a permanent Forcecage?

This depends on how the “permanent” Forcecage was created. If it was created by casting Forcecage on the same area for 30 consecutive days, it is still a “creation of magical force” and vulnerable to Disintegrate.

5. What happens if Disintegrate fails to destroy a Forcecage?

The Disintegrate spell will fail to destroy the Forcecage if some effect is granting it immunity to the spell. Otherwise, if there is nothing altering either of the spells, Disintegrate will destroy Forcecage on impact.

6. Is Forcecage concentration?

No, Forcecage does not require concentration. Once cast, it remains in effect for the spell’s duration (1 hour) without requiring the caster’s continued focus.

7. Can you cast spells through a Forcecage?

If the Forcecage is created as a solid box, no spells can be cast into or out of the area. If it’s a cage with bars, spells can be cast through the bars as normal. The cage does stop spells cast into or out of the area.

8. Can a creature escape a Forcecage using teleportation spells?

A creature attempting to teleport out of a Forcecage must first make a Charisma saving throw. On a failure, the teleportation fails, and the spell slot or effect is wasted.

9. How big can a Forcecage be?

A Forcecage can be either a 20-foot cube cage or a 10-foot cube box, as determined by the caster upon casting the spell.

10. Does a Forcecage prevent ethereal travel?

Yes, the Forcecage extends into the Ethereal Plane, blocking ethereal travel through the cage.

11. What happens to a creature only partially inside the area of a Forcecage?

Creatures only partially within the area, or those too large to fit inside the area, are pushed away from the center of the area until they are completely outside the area.

12. Is Forcecage considered a trap?

While Forcecage can be used as a trap, it’s primarily a conjuration spell designed for containment. Earlier versions of the spell required expensive ruby dust, giving it the feeling of a trap set for a powerful foe at great expense.

13. Does sunlight pass through a Wall of Force?

Yes. A Wall of Force is invisible. This means that light from one side passes through it to the other side.

14. Can a creature use Blade of Disaster to pass through a Forcecage?

Blade of Disaster is a specific rule regarding what it alone can pass through, and that’s any barrier, and that includes forcecage.

15. Can I use True Polymorph to turn a Forcecage into something else?

That is up to your Dungeon Master. As written, True Polymorph can turn a creature into an object. However, the wording of Forcecage is not as a creature or an object. So, if your DM would allow True Polymorph to be cast on a Forcecage, it would be considered a homebrew mechanic.

Conclusion

While Disintegrate and Forcecage serve different purposes, their interaction highlights the strategic depth of Dungeons & Dragons. Disintegrate provides a direct counter to the otherwise formidable Forcecage, creating a dynamic where spellcasters must anticipate and prepare for potential counterplays. Understanding these interactions is crucial for both players and DMs to navigate the complexities of the game effectively.
