In RuneScape, most players will only be able to make around 200k an hour but once you are 81+ mage and have ancients it is possible to make 400k per hour by selling these bones and hides. Read this RS gold guide, you are able to gain much RuneScape gold per hour with wonderful mood.

1.1 Requirements
To be able to dragon kill you will need atleast two 50+ stats in attack, strength, defense or ranged. It is possible to dragon kill without this but with stats on 50 it is barely possible to make 200k gold of RuneScape an hour. my stats are 83att 79str and 72 defense and can make 400k runescape gp an hour bringing 8 lobs per trip but when started on around 60att 60def 50str I needed 12-14 lobs and I could only make 200k in an hour1.2 Locations

1.2 The Slaying
Dragons are NOT hard to kill despite what some people may think, if your melee stats arent good you can range them from a distance. If you are meleeing this is what you need to wear. You could also wear some hides to protect you from the dragons breath. If you have the right outfit killing dragons is as easy as killing a chicken( it just takes longer). OR you could range them, the only safe spot is at the middle dragons and the other safe spot is in the trees.

1.3 What to Bring
NOTE im only bringing 8 lobs becuase that is all i need, if you are a lower level you may need 12-18. Bring teles depending on where you are banking.

1.4 THE REECH BECH WAY
To do this you need 81+ mage and need to be set onto ancient magicks. it is simply teleporting to carallanger (84 mage) killing the dragons and then either glory or ring of duel teleing to bank. banking this way can be shortened from a 10 minute walk to about a 30second trip. it doubles the speed you get them at and therefore doubles the money you make
If you are 84 mage you will not need the wizard mind bomb, this is the absolute fastest way to kill dragons and it is worth saving up the RS money and alching the 30k or so yew longs to get the required level

1.5 The Selling
There are 3 ways to sell
Go to world 2 bones are 2.3-2.7 each and hides are 1.5-1.9, try and get a combined 400k RuneScape gold per 100 dragon bones and hides, selling them in lots of 100 makes it alot easier
The forums - bones are under the misc section and hides are in the crafting section
Find a buyer!- find somebody who will always buy them from u at a steady price if they arent on try method 1 or 2.
