Key-Staff of Madryoch (Andrew Ochtinsky's conflicted copy 2018-09-27)

This staff of polished gold is fitted with 13 rings, each with a unique set of 24 or more symbols. The combinations are virtually limitless, enough to uniquely identify every single dimensional portal ever created, probably in the entire universe. And that is indeed its purpose.

When the right combination is selected, the staff opens a portal to the location designated by the symbols. The portal allows 2-way travel as long as the staff remains within short range of either endpoint, with the right combination showing.

Moreover, whenever the key-staff comes within 5 feet of any portal, the symbols needed to identify it begin to glow. Setting the staff to those symbols will activate the portal.

The key-staff only opens existing portals, save for the one exception: it can return to Madryoch's tower in Inupras at will. It requires no keys to open any portal, and bypasses any restrictions on portal use.
