Casting Time: 1 action
Range: 30 feet
Components: V, S, M (a drop of mercury, a dollop of gum arabic, and a wisp of smoke)
Duration: Concentration, up to 1 hour
Choose one creature or nonmagical object that you can see within
range. You transform the creature into a different creature, the
creature into an 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
transformation 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. 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.
