Madman’s Knowledge Silver Ring, inspired by Bloodborne and based on the in-game item known for granting Insight.
The original sculpt was created by Masato Ohata, capturing the distorted form of a skull with an unsettling presence. The hollow at the forehead features a slug-like haze and particles, expressed by carefully polishing blackened silver to create depth and texture. The proportions between the head and band were refined through repeated adjustments, striking a balance between strong visual impact and everyday wearability.
Each piece is finished by hand, with oxidation and polishing applied by skilled craftsmen. The inner surface is smooth for a comfortable fit, with attention given to every detail.
The inner band is subtly engraved with the material marking and an Insight icon.
The opposite side features the Bloodborne logo. The inner band is finished smooth for a comfortable fit.
The inside of the presentation box is foil-stamped with a quote from Willem of Byrgenwerth.
“We are thinking on the basest of planes. What we need, are more eyes.”
Madman’s Knowledge
Skull of a madman touched by the wisdom of the Great Ones.
Use to gain Insight.
Making contact with eldritch wisdom is a blessing, for even if it drives one mad, it allows one to serve a grander purpose, for posterity.
