Spell Description

Choose one creature or nonmagical object that you can see within range. You transform the creature into a different creature, the creature into a nonmagical object, or the object into a creature (the object must be neither worn nor carried by another creature). The transformation lasts for the duration, or until the target drops to 0 hit points or dies. If you concentrate on this spell for the full duration, the spell lasts until it is dispelled.

This spell has no effect on a shapechanger or a creature with 0 hit points. An unwilling creature can make a Wisdom saving throw, and if it succeeds, it isn’t affected by this spell.

Creature into Creature. If you turn a creature into another kind of creature, the new form can be any kind you choose whose challenge rating is equal to or less than the target’s (or its level, if the target doesn’t have a challenge rating). The target’s game statistics, including mental ability scores, are replaced by the statistics of the new form. It retains its alignment and personality.

The target assumes the hit points of its new form, and 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 the 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, unless its new form is capable of such actions.

The target’s gear melds into the new form. The creature can’t activate, use, wield, or otherwise benefit from any of its equipment.

Object into Creature. You can turn an object into any kind of creature, as long as the creature’s size is no larger than the object’s size and the creature’s challenge rating is 9 or lower. The creature is friendly to you and your companions. It acts on each of your turns. You decide what action it takes and how it moves. The GM has the creature’s statistics and resolves all of its actions and movement.

If the spell becomes permanent, you no longer control the creature. It might remain friendly to you, depending on how you have treated it.

Creature into Object. If you turn a creature into an object, it transforms along with whatever it is wearing and carrying into that form, as long as the object’s size is no larger than the creature’s size. The creature’s statistics become those of the object, and the creature has no memory of time spent in this form, after the spell ends and it returns to its normal form.

Is True Polymorph Good?

Overall Rating: Sky Blue. This means that true polymorph is an amazing spell. If you do not take this spell your character would not be optimized.

Overall Notes: This can be a crazy buff, or an extremely effective way to permanently get rid of a creature. For the buff portion, you can turn a creature into another creature whose challenge rating is equal to or less than the target's. If the creature you're transforming is a player character, the CR matches the character's level. Seeing as challenge rating is meant to match a party of four to five players of that level, you can get a huge power boost by turning into a creature that has a CR equal to your level. For example, a 20th-level character can be turned into an ancient dragon, which would typically take a party of 20th-level adventurers to defeat. On the other hand, if you target an enemy and manage to concentrate successfully for an hour, the effect can be permanent. Therefore you could turn the big bad into a rock or something. Forever.
