Blurite ore

Blurite is a rare material used only for the hilt of a sword in The Knight's Sword quest.

It is found only in the toughest dungeon mine in the free-to-play world, guarded by Ice warriors and Ice giants, located on the peninsula to the south of the Port Sarim jail.

It can be mined at level 10, but luck, skill or good defence is required to avoid being frozen out by the aggressive guardians of the Ice cave.
