It is needed to craft the following items:
Dimeritium ore is required to craft enriched dimeritium ore which is required to craft grandmaster witcher gear sets.
- Many swords found in the game contain dimeritium ore thus it can be obtained by dismantling them.
- Some higher tier swords contain dimeritium ingots which can be dismantled into ore
- However, since dimeritium ingots are required for lower tier witcher sets, they should only be dismantled as a last resort
- In the Blood and Wine expansion, they can commonly be obtained from guarded treasures and hidden treasures.
