Upheat pickaxe

An upheat pickaxe is used to mine bars from metal rocks. It, however, needs 65 Attack to wield and 90 Mining to mine with. Also it increases the players chances of obtaining an uncut oceanstone or an uncut thunderstone while mining.

Mining bars only occurs when you have other ores needed for your bar with you and have enough high smithing level. It is basically a wieldable Superheat Item spell.

If clay or coal is mined, it will result in standard mining.

Obtaining
The upheat pickaxe is a 5% drop from TzTok-Jad. It can also be made by using Superheat Item on a Dragon pickaxe. However, in 80% of cases, this will destroy the pickaxe, leaving just ashes behind.
