Modifies an *already* applied disguise on the target entity.
Like the [Disguise](/skills/mechanics/disguise) mechanic, [LibsDisguises](https://www.spigotmc.org/resources/libs-disguises-free.81/) must be installed. [Here](/Mobs/Disguises) you can find our documentation on the matter.
The syntax for the disguise in this mechanic is completely equivalent to the one used in the `/modifydisguise` command.
