PRAYER. Another tricky ability to farm for Ironman. Prayer skill requires a tremendous amount of bones or other expertise income resources for OSRS gold effective leveling. Most of the players buy them directly from Grand Exchange but not an Ironman. The best way to start will probably be questing - just as with most of the skills. Straightforward missions like The Restless Ghost, Priest in Peril, Holy Grail, and Recruitment Drive will be there to take you through the basics of Prayer skill. After this stage, you'll need to rely on farming bones to get higher levels of Prayer.
A trusted source of Prayer experience income is based inside Dragon Killing. Their bones grants considerable experience and do not demand very significant stats. To kill Blue Dragons under the Taverley (in Taverley Dungeon) you will not need much funds at all because they can be killed from a safe place. If you would like to do so, keep in mind to take action with Magic since they are weak to this specific battle style.
Use rocks, giant eggs and columns to make Dragon trapped and finish them off with your spells. Or you may also kill Green Dragons north of Cheap RS gold

the Graveyard from the Wilderness. Do not take anything too precious so that you won't miss a bank on Player Killers. You might also think of farming for Void Knight Equipment because you won't lose it by perishing with it on low Wilderness. It's a great collection for Dragon Killing and a safe one to wear in this zone.
