A Warp Nexus allows interdimensional travel to nine locations of your choice. Using the Warp Nexus while Sneaking will open up an inventory to store nine different Warp Scrolls. Using the Warp Nexus without Sneaking will open up a Warp menu to allow you to pick your destination. Warp Nexus inside Nexus Towers are situated on-top of Source Leylines so they don't require any source to operate. Once moved, a Warp Nexus requires 1,000 source per teleport.
