The Elder Scrolls Online: Rubedite Ore
Rubedite Ore is a dark red ore found in any zone. When mined, a node yields three to four samples of the raw material, Rubedite Ore. Once ten ore samples are collected, they can be refined into seven to ten Rubedite Ingots. Rubedite ingots are used for crafting pieces of heavy Rubedite Armor and weapons at any blacksmithing station. Due to the scaling of nodes in battle-leveled zones, characters will not see any Rubedite Ore nodes until their Metalworking ability is at least rank 10 or their level is at least Notes
Rubedite ingots can also be obtained by purchasing them from Imperial City merchants using Tel Var Stones.
