This DLC (Warden's Keep) reeks of Battlehorn Castle
EDIT: I just looked at the CE goodies.
"Bergen's Honor = helmet that adds +2 to armor, 25 physical resistance and 6 to attack"
"Final reason = adds to damage, fire power & fire damage"
"Grimoire of the Frozen wastes = adds +3 to all attributes when read"
Are those effects the items add as significant as they sound?
