Portals are tears between the fabric of the universe created by Wizard Grayzag that feature in the Pest Controlminigame. They spawn monsters, and must be destroyed to win the game. At the start of a game, all four portals are shielded, which makes the portal unattackable. Players will have to wait for the Void Knight to disable the shield before attacking. The first shield will go down 15 seconds into the game, and then the following shields will go down after 30 seconds. Shields go down in a random order and are announced when they do, so it is best to have small groups at each portal. The portals can be healed by spinners, and players are advised to kill these before attacking the portal. Killing one portal will heal the Void Knight, and also any spinners that were trying to heal it.
