When Sten shows you how, Suak will tell you what kind of RuneScape gold armor to make. If you follow the instructions he requires, you'll be awarded a bonus exp reward. If Suak's armor request is changed, go to the anvil, choose that armor piece, then keep working.
To make Runescape Burial Armor It is necessary to require a hammer as well as iron, steel, mithril, the adamant or rune. The smithing requirement is 30 because this is the minimum requirement to work with Iron ingots. For working with steel, you'll need Level 45 Smithing. Level 60 for mithril. Level 70 for Adamant, and level 90 for Runite.
While it may seem cheaper to work with iron the process is really slow. With Iron Grade I, you'll receive 40,000 experiences per hour. However, if you're using Steel Grade I, you'll have 50,000 experience in an hour. The more valuable the metal a greater grade you use, the more smithing experience you'll acquire.
For making burial armor first, create normal armor on the anvil close to the anvil for burial. You'll then have to go to the artisans' anvil and make the necessary changes into cheap RS gold burial-grade armor. After the armor has been upgraded, it'll automatically go down through the chute next towards the theanvil.
