Traveling is the ability that an Incubus, Succubus, and Vex possesses. It's the ability to "Rip" or teleport to any place the Incubus or Vex wants although there are some limitations. Traveling functions the same way as "teleportation." Casters have been proven to be able to Rip as in the case of Lennox Gates using Rip Letters. Link describes it as like being sucked up in a vacuum cleaner.
