Orichalcum is a crafting component introduced in the Blood and Wine expansion. It is only needed to craft orichalcum ore, and can also be dismantled from it.
It can be found in many places both as random and guaranteed loot, and can be purchased from the following merchants:
- Armorer in Hauteville
- Blacksmith in Belgaard Manor, after he is rescued
- Lazare Lafargue in his workshop
- Trentin in his workshop in Hauteville
