Roranach's Horn is a helmet which offers the wearer 50% resistance against damage from crushing damage. It can be used by Cespenar to upgrade the Staff of the Ram.
It is dropped by Gromnir Il-Khan when he is killed in the first chapter of Throne of Bhaal.
|“||This helm is carved from the horn of a great ram. Etchings on the horn suggest the beast was once worshipped by ancient barbarian tribes.||”|
