What is Polymorph?

Polymorph (PHB, p. 266) is a 4th level transmutation spell, which is available natively to Bards, Druids, Sorcerers, and Wizards. It requires vocal, somatic, and material components with the latter being a caterpillar cocoon. It requires an action to cast, when you do so you choose a creature within 60 feet and attempt to change them into a new form. If the creature is unwilling it must make a Wisdom saving throw to resist the spell’s effects, but a willing creature is affected normally. You can change the affected creature into a beast of your choosing, as long as their level or challenge rating, whichever applies, is equal to or higher than the beast you have chosen. For example, you can turn a 5th level character into brown bear because its CR is only 1. However, this spell can’t transform a shapechanger or any creature that currently has zero hit points. This new form lasts for up to 1 hour, or until the caster loses concentration or the beast form is reduced to zero hit points.

Whilst in this new form, the creature’s clothing and equipment meld into their body, making them unable to benefit from it, or any of the normal features they may have from a class or race including spellcasting, speaking, or taking any actions that require speech or hands. The creature adopts the new form’s stats entirely, including the mental stats and any actions or abilities the form may have. If reduced to 0 hit points whilst in this form, the creature reverts to its own body, and any remaining damage is carried over to its own hit point total. For example, if a beast form has 7 hit points and takes 10 points of damage, the creature would revert to its original form and take 3 points of damage.

Is Polymorph a good spell?

Polymorph is an excellent spell that can really change the kind of encounters a party is able to tackle once it becomes available. The spell can be used in three primary ways: to turn a monster into a more vulnerable target, to turn an ally into a more durable/damaging form in combat, or to turn an ally into a form for utility purposes. Whilst the notion of turning a dangerous creature into a harmless critter is amusing and can be very successful, it is the least reliable way of using this spell. Even a creature with a low Wisdom score can get lucky and many creatures will have features that increase their chances of success, some creatures are even immune to its effects. The latter two options are generally the most advised way of using Polymorph, such as polymorphing an ally into a giant eagle to carry the party across a chasm, or into a giant ape to tank damage and potentially deal it. The main hangup of using this in combat on allies is potentially making them vulnerable to mental saving throws or fighting enemies that are resistant or immune to the beast form’s nonmagical damage.

If you’re looking to improve this spell, then there are a few avenues you can take, but the most recommended is to ensure that you have a robust Constitution saving throw to maintain concentration on it, such as taking the Warcaster or Resilient feat and choosing Constitution. Sorcerers have a variety of Metamagic options that can improve the potency of Polymorph, such as Twinned Spell to transform two targets, Extended Spell to have a utility form last longer, and Heightened Spell to give a hostile target disadvantage on the Wisdom saving throw. Another way of improving it is with the Divination Wizard’s Portent feature, allowing you to substitute a low roll you may have for their Wisdom saving throw. These are just a sampling of how to improve this spell, so explore and experiment!

How to roleplay the Polymorph spell

Need some help roleplaying the Polymorph spell? Here are some examples to help you out:

  • Your character points at the enemy, and with a flick of your wrist, you cast the Polymorph spell. The enemy’s form begins to change, their body contorting and twisting as they are transformed into a small, helpless creature, such as a frog. You chuckle as you watch them hop around helplessly, knowing that they are now at your mercy.
  • Your character calls forth the power of the Polymorph spell, transforming themselves into a majestic beast such as a giant eagle or a fierce lion. You feel the power of the animal coursing through your veins, and you revel in the freedom of being able to fly or run at incredible speeds.
  • As your party confronts a group of enemies, you cast the Polymorph spell, transforming one of the enemies into a harmless creature such as a squirrel. The other enemies are momentarily stunned as they watch their companion scamper off, leaving them vulnerable and confused.
  • Your character faces off against a terrifying dragon, but you know that you have a secret weapon – the Polymorph spell. You concentrate your power, casting the spell and transforming the dragon into a harmless creature, such as a kitten. The once fearsome creature now meows and purrs innocently, and you can’t help but laugh at the absurdity of the situation.
