Upon casting this spell, the caster's form is transmuted into that of a Wingless Wonder, as per the creature's stat block, with the following exceptions:

• The caster retains their own mental statistics (Intelligence, Wisdom, and Charisma).

• The caster retains their spellcasting features and can cast spells without the need for somatic or verbal components. Material components are stored and then later consumed from within the caster's transformed body.

Drawbacks:

• Diminished Intellect: For each hour the caster remains in this form, an Intelligence saving throw (DC 15) must be made. Failure results in a loss of 1 point of Intelligence. If the caster's Intelligence score reaches 3, they become a Wingless Wonder under the DM's control.

Ending the Spell:

• The spell can be terminated early by using a bonus action on the caster's turn, resulting in an immediate reversion to the original form.

• If the caster becomes a Wingless Wonder permanently, only this spell or a Wish spell can revert them to their original form. Upon reversion, the caster's memories of their time as a Wingless Wonder will remain intact.
