A transform is a skill type that turns the user or target into something else. While transformed, the target is given an alternate set of skills for the duration of the effect. Most transform skills are replaced by "Leave Form" skill which allows the user to exit the transformed state manually. Profession skills that provide transform effects but do not have the Transform skill type are listed as well.
Many skills, items, or activities that provide transform effects. For example, you will be transformed into various animals during the Champion of the Sun meta event.
