Can You Polymorph Into a Mind Flayer? A Deep Dive into D&D’s Transformation Magic

The short answer is a resounding no. The Polymorph spell, in its various iterations across different editions of Dungeons & Dragons, restricts transformations to creatures of the Beast type. Mind Flayers, also known as Illithids, are classified as Aberrations. Therefore, using spells like Polymorph or even True Polymorph to transform into a Mind Flayer is strictly against the rules as written (RAW). However, the magical world of D&D is vast and full of possibilities, so let’s explore the nuances and limitations of transformation magic when it comes to these tentacled terrors.

Understanding Polymorph and its Limitations

The Core Mechanic: Beasts Only

The Polymorph spell, a staple for spellcasters in D&D, allows a character to transform themselves or another creature into a Beast. The specific rules vary slightly between editions, but the core limitation remains consistent: you can only become a Beast. This is crucial because creature types in D&D define the fundamental nature of a being. A Beast is a natural creature, often an animal, while Aberrations are beings from beyond the natural order, often linked to the Far Realm or other planes of existence. Mind Flayers, with their psionic abilities and grotesque physiology, firmly belong in the Aberration category.

Challenge Rating (CR) Restrictions

Even if you could target an Illithid with Polymorph (you can’t!), there is a restriction on Challenge Rating (CR). The spell typically limits the transformation to a beast whose CR is equal to or less than the target’s CR or level. This ensures that players cannot simply turn themselves into incredibly powerful creatures. The highest CR beast usually cited is the Tyrannosaurus Rex (CR 8), a far cry from the challenge posed by a Mind Flayer, which typically has a higher CR, especially with enhancements or unique abilities.

True Polymorph: A Glimmer of Hope? Not Really.

The True Polymorph spell offers a greater range of possibilities, even allowing transformation into other creature types, and even objects!. However, the Dungeon Master (DM) has final say, and even True Polymorph may not always be enough to transform you into a Mind Flayer.

Beyond Polymorph: Other Transformation Methods

While Polymorph is out of the question, other magical effects exist that might seem like a transformation into a Mind Flayer, even if they aren’t.

• Illusions: A clever illusionist could create the appearance of a Mind Flayer, but this would only be an illusion, not a true physical transformation.

• Wish Spell: The Wish spell, the most powerful in D&D, can potentially alter reality to allow for such a transformation. However, using Wish in this way is risky, as it can have unintended consequences or strain the caster’s abilities.

• DM Fiat: Ultimately, the DM has the power to change any rule or introduce new magical effects. A DM could theoretically allow a player to transform into a Mind Flayer through a custom spell or magical item, but this would be a significant deviation from the standard rules.

Thematically Speaking: Why No Mind Flayer Transformation?

Beyond the mechanical reasons, the idea of a player character (PC) simply transforming into a Mind Flayer is often thematically problematic. Mind Flayers are inherently evil creatures, driven by a hunger for brains and a desire to dominate other beings. A PC who becomes a Mind Flayer would likely undergo significant personality changes, potentially becoming an antagonist rather than a player character. The narrative implications are complex and often disruptive to the game. Furthermore, Mind Flayers represent a fundamental horror element within the D&D universe. Making them easily accessible through a standard spell diminishes the impact of encountering them.

Frequently Asked Questions (FAQs)

1. Can I use Wild Shape to become a Mind Flayer?

No. Wild Shape, a Druid ability, is even more restrictive than Polymorph. It only allows transformation into Beasts that the Druid has seen, further solidifying the impossibility of becoming a Mind Flayer. As explicitly stated, “An owlbear is a monstrosity, and a druid can only turn into beasts with Wild Shape.”

2. What is the strongest creature I can Polymorph into?

The Tyrannosaurus Rex (CR 8) is generally considered the strongest creature that can be turned into via the Polymorph spell. However, the specific “strongest” beast depends on the context of the situation and the needs of the character.

3. Can I True Polymorph into a Dragon?

This is a common question. True Polymorph can turn you into a Dragon if the dragon’s CR is equal to or lower than the target’s level.

4. If I True Polymorph into a powerful creature, do I keep my class abilities?

No. When you are True Polymorphed, you adopt the statistics of the new form, including its abilities, hit points, and skills. You do not retain your class features or spells.

5. Can I use Shapechange to become a Mind Flayer?

Similar to True Polymorph, Shapechange allows transformation into various creatures. However, the same limitations apply: Mind Flayers are Aberrations, not Beasts.

6. What happens if I’m Polymorphed into a creature that gets killed?

If the form you were polymorphed into is reduced to 0 hit points, you revert back to your original form with your original hit points. Any excess damage may carry over, depending on the specific spell and the DM’s interpretation.

7. Can a Mind Flayer be Polymorphed?

Yes! While you can’t become a Mind Flayer with Polymorph, a Mind Flayer can be targeted by the spell. This could be a useful tactic for a party of adventurers facing off against one of these creatures. This negates their abilities, and they have no innate ability to remove this curse.

8. Can I Polymorph myself into an object?

No, Polymorph is restricted to Beasts. However, the True Polymorph spell does allow transformation into objects.

9. Can I Polymorph a dragon? Are they immune?

Dragons are generally not immune to Polymorph. However, many dragons have high saving throws and legendary resistances, making it difficult to successfully cast the spell on them. Dragons also have some innate powers over the element they are linked to. For example, a red dragon (fire) will have some control over fires.

10. Can I Polymorph into a giant?

No. Polymorph can’t turn creatures into a giant. Of course not every puzzle, problem or situation in an adventure needs to have a solution in the PC’s arsenal of spells and abilities. There are “locks” meant to be “picked”.

11. Can I Polymorph a werewolf?

The werewolf can use its action to polymorph into a wolf-humanoid hybrid or into a wolf, or back into its true form, which is humanoid. Its statistics, other than its AC, are the same in each form. Any equipment it is wearing or carrying isn’t transformed. It reverts to its true form if it dies.

12. Can I Polymorph into an Owlbear?

No. An owlbear is a monstrosity, and a druid can only turn into beasts with Wild Shape.

13. Can a Mind Flayer transform into a Lich?

Only the most powerful mind flayer mages could achieve true lichdom and were known as illithiliches; however, many in the Realms did not make this distinction.

14. Can a Mind Flayer levitate?

Yes! They’re resistant to spells and other magical effects, and in addition to dominate monster, they can also cast detect thoughts and levitate at will and plane shift once per day on themselves.

15. Who controls Mind Flayer?

When the Mind Flayer was introduced in Stranger Things season 2, it presented one of the monster’s most distinct abilities: the hive mind. As the ruler of the Upside Down, Vecna had full control over the creatures from the other dimension, including the Mind Flayer.

Conclusion

While the allure of transforming into a Mind Flayer may be strong, the rules of D&D, and thematic considerations, prevent it through common spells like Polymorph. Focus on more rules-abiding transformations, or perhaps find an extremely generous Dungeon Master, and you may get to feel the joys of being a tyrannosaurus rex, and other beast.
