It's the most efficient Smithing training method in OSRS, offering both high XP rates and profit potential depending on the bars you make. Located in the Dwarven city, it requires The Giant Dwarf quest to access.

- 60+ Smithing (to use for free, otherwise 2,500 GP/10 min)
- Ice gloves (Heroes' Quest or NMZ - instant bar pickup)
- Coal bag (Motherlode Mine, 100 nuggets - holds 27 coal)
- Goldsmith gauntlets (Family Crest - 2.5x XP for gold bars)
- Stamina potions (maintain run energy for max efficiency)
