Superheat Form is part of the Seren Prayers that supplement the Ancient Curses. They are unlocked upon completion of The Light Within. Superheat Form requires 91 Prayer to use. It will automatically burn logs while Woodcutting and smelt ore while Mining when active and gives the experience for those actions, assuming you have the level and coal (for mining) required to do so. Coal inside of a Coal Bag will be used before any coal in your inventory. Logs and ore withdrawn or picked up will not be burned or smelted and will not yield any experience.
Superheat Form does not work in conjunction with Sign of the porter as the Sign will take priority and send off the ore before being smelted.
Superheat Form will work with urns, filling them normally. It currently does not fill Smelting urns when using Superheat Form at gold ore rocks or concentrated gold deposits (despite an update that allowed gold to fill urns). It is not known whether it is a bug or intentional.
The use of Prayer renewal with any Prayer bonus item will completely counteract the drain from this curse.
