Roranach's Horn

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 an item, but this is not confirmed.

This item appears in Baldur's Gate II: Throne of Bhaal and Baldur's Gate II: Enhanced Edition. It might have been dropped by Gromnir Il-Khan when he is killed in the first chapter of Throne of Bhaal.

In-game description
"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."
