"A piece of armor made from a rare alloy. It looks very old."
This piece of armor is found in a sarcophagus in the crypt near the Lakeside in Murky Waters. The first time Geralt enters this crypt, he finally encounters Berengar face-to-face and is able to ask a few questions. It is one of the pieces used to recreate Raven's armor.
- It is unclear if this is the piece of Count de Ruyter's armor that is mentioned or some other piece, as nothing is ever identified explicitly as being "Count de Ruyter's armor".
