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. Selling this will also update players' Ardougne Tasks. 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 generate 150 life points of damage to Mogres whilst luring. During Salt in the Wound, Ezekial utilizes homemade Rubium grenades as his primary weapon.
