As you begin you'll want to purchase some Mind Runes and
RuneScape gold Air Staff. This allows you to use one of Strike Spells - Wind Strike. Take on Goblins to the east of the castle or Cows on the farm's northeast.
Buy Cosmic Runes Staff of Water for Water Runes and Sapphire Rings. When you cast the Enchant Ring you can make Rings of Recoil which is an item that sells well and will earn you a more money to buy new Runes. It will take a around 500 castings in order to reach level 27 before you can begin a new process.
Starting at level 27, you are able to use level 2 Enchant spell. This spell can be used on Emerald Rings to create Rings of Duelling. Shopping for Cosmic Runes and Staff of Air might be required. You can repeat this incantation 1,000 times to get the level 43. This should take you about an hour.
After you cast Curse spell on your opponent, it has a timer which has to run out before it can be used on the same person. This timer can be bypassed by splashing as it won't be a negative effect on the victim. Make sure you have a to have a negative Magic stat. The Monk from Zamorak located in Varrock Palace is commonly used as a punching bag by RuneScape players. You can take the inmate to an arena and curse him for a bit.
Within RuneScape you can use Superheat on ores in order to create bars of
cheap OSRS gold them. e.g. casting it on Gold Ore will result in making Gold Bars. However, if you don't wish to invest too much, I suggest doing this with Iron Ores.
