Superheat Item

Superheat Item is a non-combat Magic spell used to smelt Ore without a Furnace. The spell requires four Fire Runes and one Nature Rune to cast. You can replace the Fire Runes with a Fire staff however. Casting Superheat Item creates only one bar, and cannot be cast upon noted ores. The ore amount required is the same as if you were smelting the bar in a Furnace.

The same Smithing level is required to superheat ore as the level required when smelting in a Furnace. For example, your Smithing level must be 50 if you wish to superheat the ore for a Mithril bar, and to superheat ore for a Rune bar, your Smithing level must be 85.

53 Experience Points is rewarded to you in the Magic skill, and the normal Smithing experience is rewarded as if you were smithing the bar in a furnace.

Smelting a bar that requires Coal is a little different, for you cannot click on the coal ore itself, but instead you must click on the primary ore for the bar that you wish to create. For example, to smelt a Mithril bar, you must click on a Mithril ore in your inventory in order to superheat a Mithril bar.

Furthermore Superheat Item guarantees a one-hundred percent success when smelting Iron ore into an Iron bar, however when smelting with a Furnace only yields a 50-80 percent success rate depending on your level in Smithing.

Superheat Item cannot be used to make jewellery or Cannonballs, but does allow one to create Gold bars as well as silver bars and any other metal bar.

Trivia

 * Attempting to cast Superheat item on a non-ore object will result in the message "You need to cast superheat item on ore."
