Runescape Power Leveling can mean two different things. A Google search will find all kinds of sites with that will train your account for you. This breaks rule 6, but several people still do it. The majority of these sites are just after your password. They will charge you a certain price in real money, and then they get your account password. This is as risky as it can get. Most of these sites will offer “Live Help Agents” that you can talk with to help you with your “orders”. They will just reassure you it doesn’t break any rules and convince you to pay them money.
Goblins are excellent for low and high levels. They are easy to kill and give a nice amount of exp. Remember; you want quick and easy kills that give fair experience points, instead of slower kills and more experience. The reason is, with fast kills you can double and triple the experience in the time it takes to kill the higher level. Goblins are perfect for this. They are dead in about two to three hits and then you can be on to the next one.
The Stronghold of Security can be very fun, especially if you have not done it before. At the end of each level, there are rewards. For just the first level, you get 3,000 gold! The prizes just go up from there. If you are power leveling, no matter where, you are most likely going to need food. I highly recommend Tuna. They do not cost too much cooked and they heal about 10 points each. Carry around some Tuna, and it might save your life.
