A Teleportation License allows you to instantly travel to towns, players and zones, that you have visited at least once, as well as friends and party members, via teleportation. Teleportation to Rome and Antillia is always free. There is also an Allied Teleportation License, which is more limited, but considerably cheaper. 20% Will is required to teleport, except for quest teleports, which are build into the quest log. These still require a teleportation license, but require 0 Will.
