Superheat Item

Superheat Item is a non-combat Magic spell used to smelt ore into bars without the use of a furnace.

This spell is cast on one ore in the player's inventory at a time. The required amount of coal (if needed) and Smithing level are the same as if smelting the bar in a furnace. Each cast grants the player 53 Magic experience and the corresponding Smithing experience as would be granted if smelting the bar at a furnace. The experience-boosting effect of the goldsmith gauntlets/Smithing cape is applied when casting Superheat Item.

Casting Superheat Item on iron ore while having at least two pieces of coal in one's inventory will produce a steel bar. Otherwise, it will produce an iron bar with a 100% chance of success, as opposed to smelting it in a furnace, which only yields a 50% chance of producing a bar. This is comparable to a ring of forging, which provides 140 bars at 100% success rate and is much cheaper when taking into consideration the number of uses it has. However, players who use a ring of forging must still walk to a furnace, whereas with Superheat Item players can stay at the mine/bank and skip running to the furnace altogether.

Casting at mines[edit | edit source]

If players plan to mine both coal and an ore that requires it at the same mine, using Superheat Item can help free up inventory space by using up the mined coal to create bars. The time saved by not having to make as many trips to the bank could be considerable: an almost full inventory of bars could be made in one trip rather than requiring one trip for an inventory of ore and several loads more for the coal to smelt it with. Other factors to be considered are weight and running; bars weigh slightly less than ore, so players who use this method can run for longer. However, using this method requires two of the player's inventory spaces be reserved for fire and nature runes, so players who use this method should know that they will be bringing slightly fewer bars to the bank each trip.

Another use of Superheat Item is to cast it at the Coal Trucks. Example using mithril: Instead of 5 to 7 trips to empty the coal trucks in the Seers' Village bank, players can take a pickaxe, 22 mithril ore, nature runes and an equipped fire staff or equivalent and leave 4 inventory spaces open. Repeatedly fill the slots from the coal trucks and cast Superheat Item. In this way only two trips to the bank are required to smelt an inventory of mithril bars.

Other uses[edit | edit source]

Another use is to cast Superheat Item when killing creatures that drop the ores and coal to save inventory spaces or the need to bank or drop them, an example could be a slayer trip to Rockslugs or Desert lizards.

Superheat and enchant jewellery spells will now queue up one spell if you cast them too quickly.

Trivia[edit | edit source]

  • Attempting to cast Superheat Item on a non-ore object will result in a chatbox message stating, You need to cast superheat item on ore, and a splash animation will appear on the player.
  • Attempting to cast Superheat Item on an Elemental ore fails and will result in a chatbox message stating, Even this spell is not hot enough to heat this item.
