Disorienting Portal is a 10th-level ritual.[DCD:84] You create a shortcut across the world. Other than as described here, this ritual functions like Linked Portal. The teleportation circle must be inside a doorway or similar opening that connects to another doorway or opening within 50 squares (250 feet), which you designate when you perform the ritual. The doorways can each be up to 4 squares in width. As part of performing the ritual, you must adorn the door frame or perimeter of the portal with various sigils and runes.
