Rune Helm = 1000 Iron Ore (OR 600 Coal)
Rune Legs = 1500 Iron Ore (OR 900 Coal)
Rune Kite = 1200 Iron Ore (OR 720 Coal)
It is recommended to get iron ore, seeing as it's ALOT easier to mine; But it would be more efficient for higher levels to mine Coal, because it would be just as easy as iron ore. It is your choice, BUT I will not accept mixed payments (Example: 500 iron ore, and 300 coal for a Rune Helm.) I do, however, accept mixed methods of payment for individual items (Example: 1000 Iron Ore for the Helm, and then 900 Coal for the Legs, etc.)
Good Luck!
