The best method for starting is to RuneScape gold start questing - much as you would with all of the abilities. Easy missions such as The Restless Ghost, Priest in Peril, Holy Grail, and Recruitment Drive will help you master the fundamentals of Prayer skill. Following this point you'll need to depend on the farming of bones in order to attain higher degrees of Praying.
A reliable source of Prayer experience revenue is Dragon Killing. The bones of Dragon Killers provide significant amount of experience and don't require very high stats. To take out Blue Dragons below the Taverley (in Taverley Dungeon) you don't require any resources whatsoever since they are able to be killed in a safe place. If you do decide to do this, make sure to use Magic since they're weak to this particular style of combat. Use huge eggs, rocks and columns to get Dragon stuck, and then complete them with your spells.
Alternately, you could kill Green Dragons north of the Graveyard in the Wilderness. Make sure you bring an Anti-Dragon Shield, food and equipment. Don't take anything too precious so that you don't risk losing a bank on Player Killers. It's also worth considering farming in search of Void Knight Equipment as you're not likely to lose it falling victim to it while in low Wilderness. It is an excellent outfit that is ideal for Dragon Killing and a safe one to use in this zone.
The bones you gather must be sacrificed at the Chaos Altar, but it is not a safe method therefore, don't carry anything other than the bones you'd like to sacrifice. This place is one of the most Player Active zones on Runescape It is located on the 38th level of rs 2007 gold Wilderness.
