Dimension Invasion is a party quest requiring level 140 to join. It can be completed solo or in a party of up to 4 players. You may only enter Dimension Invasion 5 times a day. Dying, leaving, or getting booted from the party quest due to not killing the monsters fast enough; this will count towards the 5 count limit. The level of the monsters in the party quest will be the average level of all party members, rounded down. It can be accessed via the Dimensional Mirror.
