Gold Ardeo is a Head Attire in Bloodborne. It is part of the Executioner Set.
" The odd helmet worn by the band of Executioners commanded by the martyr Logarius.
The conical gold helmet, symbol of the executioners, represents luminosity, ambition, and an unflagging resolve to face impurity, staring it down with stern golden spirit.
As the great Logarius once said, "Acts of goodness are not always wise, and acts of evil are not always foolish, but regardless, we shall always strive to be good."
