You may also want to do Mountain Daughter, doing this in combination with Death Plateau will get you very close to 20 Attack, and you get the bearhead mask from Mountain Daughter. However, you may not want to do it because you also get 2k prayer xp from it which gives you 13 prayer; and you don't have to actually finish Mountain Daughter to get the Bearhead. It's a good idea to get your woodcutting up because obby pures can take a lot of cash. If you want range, you'll buy rune knives which are 2k each, you need to buy range pots then, and super strengths, and sharks, and you'll want an obby necklace (2.5m), and possibly an Unholy book (1.8m).
