Silk Thread

The Silk Thread is a quest item in the game Castlevania: Order of Ecclesia. They can be found inside of rare chests in Kalidus Channel, or in common chests in Misty Forest Road, Skeleton Cave and Somnus Reef. They can also be dropped by Arachnes.

Five of them must be brought to Monica in order to complete her second quest: Silkorm's Tragedy.

She'll reward you with a Silk Dress (DEF +15, INT +2, MND +5); and also both, the Empire Dress (DEF +20, INT +5, MND +7) and the Corset Dress (DEF +20, INT +6, MND +12), will become available at Jacob's shop for purchase.
