Empty House

is a Noble Phantasm of Sherlock Holmes. It allows him to disguise himself as other individuals, including Heroic Spirits. It is not a perfect imitation, since the parameters he imitates cannot exceed his own parameter values, and he cannot use the skills and Noble Phantasms associated with Heroic Spirits he imitates.Fate/Grand Order material V - Sherlock HolmesFate/Grand Order: Epic of Remnant - Shinjuku Phantom Spirit Incident: The Malignant Quarantined Demonic RealmFate/Grand Order - Sherlock Holmes, Valentine's Day
During the events of the Shinjuku Singularity, Holmes used Empty House to disguise himself as Edmond Dantès. He was recognised as a fake when he referred to himself as Edmond Dantès, instead of The Count of Monte Cristo.
