D&D 5e – Polymorph Spell – Is it Overpowered?

So during my lunch break yesterday, I was reading posts on some of the message boards, and I saw an interesting topic. The topic of the Polymorph spell came up being overpowered and was being restricted from use by some DMs. A spell being restricted from a campaign? Sounds weird… So what character class uses polymorph? Polymorph is a 4th level transmutation spell that is usable by wizards, druids, and bards when they reach level 7. For Wizards it also usable for free without expending a spell slot when a Wizard of reaches level 10 of the School of Transmutation.  Seems reasonable for a Wizard in the school of transmutation to have that power. But let’s look at the spell’s description:

Polymorph Spell

4th-level transmutation
Casting Time: 1 action
Range: 60 feet
Components:V,S,M (a caterpillar cocoon)
Duration: Concentration, up to 1 hour
– This spell transforms a creature that you can see within range into a new form. An unwilling creature must make a Wisdom saving throw to avoid the effect. A shapechanger automatically succeeds on this saving throw.
– The transformation lasts for the duration, or until the target drops to 0 hit points or dies. The new form can be any beast whose challenge rating is equal to or less than the target’s (or target’s level, if it doesn’t have a challenge rating). The target’s game statistics, including mental ability scores, are replaced by the statistics of the chosen beast. It retains its alignment and personality.
– The target assumes the hit points of its new form. When it reverts to its normal form, the creature returns to the number of hit points it had before it transformed. If it reverts as a result of dropping to 0 hit points, any excess damage carries over to its normal form. As long as the excess damage doesn’t reduce the creature’s normal form to 0 hit points, it isn’t knocked unconscious.
– The creature is limited in actions it can perform by the nature of its new form, and it can’t speak, cast spells, or take any other action that requires hands, or speech.
– The target’s gear melds into the new form. The creature can’t activate, use wield or otherwise benefit from any of its equipment.

Doesn’t look that powerful for a 7th level character.  So at level 7 you can transform anything into a beast form.  Even a bad guy, but I would look for enemies with low wisdom. and decommission them for an hour. But only up to the creature’s CR or level.  So what creatures are beast?  Below are all the beasts, but I’m only really interested in the last one, the Tyrannosaurus Rex!  Change yourself or your ally into The Tyrannosaurus Rex!!! Holy Cow! I wanna be a T-Rex!!!! But have to wait till level 8, or have an ally at level 8+. I can’t WAIT!


Tyrannosaurus Rex
Huge beast, unaligned
Armor Class 13 (natural armor)
Hit Points 136 (13d12 + 52)
Speed 50 ft.
STR 25 (+7)DEX 10 (+0) CON19 (+4) INT2 (−4) WIS 12 (+1) CHA 9 (−1)
Skills Perception +4
Senses passive Perception 14
Languages —
Challenge 8 (3,900 XP)

Multiattack. The tyrannosaurus makes two attacks: one with
its bite and one with its tail. It can’t make both attacks against
the same target.

Bite. Melee Weapon Attack: +10 to hit, reach 10 ft., one target.
Hit: 33 (4d12 + 7) piercing damage. If the target is a Medium
or smaller creature, it is grappled (escape DC 17). Until this
grapple ends, the target is restrained, and the tyrannosaurus
can’t bite another target.

Tail. Melee Weapon Attack: +10 to hit, reach 10 ft., one target.
Hit: 20 (3d8 + 7) bludgeoning damage.

Sounds awesome, but how does that concentration work if you polymorph into a T-Rex and stomp around biting stuff, but have to maintain concentration, and can’t cast anymore spells. So to maintain concentration, with the Trex’s high Constitution, you get a +4 against a DC 10 or half of the damage you take.  So let’s say, if you’re fighting another wizard that changed into a TRex and he bites you.  That DC could easily be 16 (or even 27 at max damage) from the Trex bite damage which means you lose concentration and revert back to normal form.  Doesn’t sound OP so far, because concentration could be lost.

But what if Bless and Stoneskin are cast on the T-Rex to maintain the form?  Then a 1d4+4 is added to the d20 roll, and the other TRex is biting but only causes half damage, so then the DC drops to the low setting of 10.  Not hard to overcome with a d20+d4+4.  But throw in a giant with a +1 weapon, causing major damage and the stone skin doesn’t help like that anymore.  DC shoots up, way above the low setting, and chances increase on losing concentration.

And if its a Wizard, he becomes basically a huge melee fighter in the front, and doing 53 points of damage on hits with a +10 to hit. Not bad, but this also has the added risk of being in the front line if he loses concentration, and then all that damage gets transferred to his frail little body.  Hmmmm… So far I’m not seeing it becoming OP.  But maybe I’m overlooking something.  You can’t benefit from any of your equipment, still can’t use feats, abilities, or features.  Might be good,  but once you get up in levels, I don’t think this spell will be as useful as other powers that a character may have.

Thanks for reading, and please share. Have fun!
