First off getting there. Go to your spell book and click Minigames, then click PC. You should now be on an island. Walk all the way south and cross the gangplank.

You will most likely not be able to solo Pest Control so you will want to bring a good team. I have brought along Andrew and Nglatzhofer to help me with it.
[You must be registered and logged in to see this image.]Once you are inside the game there are four portals. East, Northeast, Northwest, and West. Choose a portal and go for it. It would be better for the team to split up and each get their own portal.
[You must be registered and logged in to see this image.]Now, you will get 5 points for every game you win along with 500,000 gold pieces. Here is the list of what you can buy with your points
[You must be registered and logged in to see this image.]To get Experience you need 20 points until you can exchange. The amount of experience you gain all depends on what level your skill is. It varies from 15,000 experience to around 1,400,000. Yes, you can gain experience in a skill once it has reached 99!
For the Void Knight armor!
Void Mage Helm - 100 points
Void Ranger Helm - 300 points
Void Melee Helm - 300 points
Void Knight Bottom - 250 points
Void Knight Top - 250 points
