Rubium is an ore that players can only mine deep within the Witchaven Dungeon at the Witchaven mine during and after the Kennith's Concerns quest.

Rubium has high reactivity with water. Thus, during the quest, it is used on the steamers to raise the room temperature significantly in order to disrupt the workers. However, the rubium will burn up if players get kicked out, so they still need to be careful not to get caught. After the quest, players may sell rubium to Ezekial Lovecraft in his fishing shop, based in Witchaven for 10 coins per ore. Doing this is required for the medium Ardougne task 'Volatile Valuables'. During Salt in the Wound, Ezekial utilises homemade rubium grenades as his primary weapon.

Players may also mix it into a guam potion (unf) at 31 Herblore to make a Super fishing explosive. Super fishing explosives give 55 experience to make and will damage mogres for 150 life points whilst luring.

In total, there are only twelve rubium veins located in the mine, requiring 46 Mining to be mined and yielding 17.5 experience points for each successful dig, the same experience as mining the low-level ores copper, tin and blurite, thus making it useless unless attracting mogres. It cannot be mined with the Dwarven Army Axe.

100 rubium is needed in order to fill the super explosive flask to make the super explosive shaker.

Rubium will respawn when a player leaves and reenters the mine room.

Players can access the mine by entering the ruins and taking the entrance directly east and follow the cavern through (use of shortcut with the required agility level) and use the entrance option located just before the open doors.

Trivia

• Rubium may be based on the real-life metallic element rubidium, which is also highly reactive with water and chemically unstable. Although rubidium is a silvery-white Group I alkali metal, it burns with a reddish-violet colour in a flame. In contrast, rubium is directly coloured as red. However, its reactivity is a closer match to Sodium.
• Despite its high reactivity with water, using it on any water source (sink, well, etc.) or any container of water (bowl of water, bucket of water, etc.) only yields this message: "Nothing interesting happens."

Players can mine rubium from the walls in designated parts of the dungeon under Witchaven.
