The purpose of runescape accounts for sale is to try to reach an artifact that you can trade for 1000 pieces. Other methods include using a teleport home (if your house is in Rellekka), slayer ring teleport, or Enchanted lyre teleport, then walk northeast to the boat.
The course is located northeast of the Tree Gnome Stronghold. Make sure you buy runescape accounts and have plenty of food and you have not made all kinds of weapons, shields, or cap (basically just come naked with weight reduction gear other than a cape). The only absolute defence against a particular attack is the Protect from Melee prayer (which has 100% chance of success). Chainmail armour is weaker against stabbing; platemail is weaker against crushing, while the slash attack is highly effective against cloth.
The Ape Atoll is one of the most popular courses that almost everyone with a high level of agility has trained in the frame.
