Skull Shield

Like its twin brother, the Skeleton Shield, the Skull Shield is of jagged shape and features a grim demonic face meant to intimidate the opponent.

Skull shields don't appear to be highly changed by dyes; they change color in the cracks and crevices (the brown parts in the picture), but it's a bit hard to tell unless you use a contrasting/bright color.

In Pre-sear, Skull shields can drop from char found north of the wall. These typically have no requirement and are armor level 7.
