Transformation lasts 8 hrs until target uses a bonus action to transform back into its true form or until target dies. Items target is wearing/carrying are absorbed into new form. In new form target retains its alignment and Int Wis and Cha scores as well as its ability to speak. Its other stats are replaced by those of its new form and it gains any capabilities that new form has but it lacks.
