The Badge of a Pathfinder
A small magical device patterned off ancient relics of a long lost civilization, a wayfinder is typically made from silver and bears gold accents. With a command word, you can use a wayfinder to shine (as the light spell). The wayfinder also acts as a nonmagical (magnetic) compass, granting you a +2 circumstance bonus on Survival checks to avoid becoming lost. All wayfinders include a small indentation designed to hold a single ioun stone. An ioun stone slotted in this manner grants you its normal benefits (as if it were orbiting your head), but frequently reveals entirely new powers due to the magic of the wayfinder itself.
The wayfinder is a blend of artistry, magic, and technology. Reverse-engineered from half-understood artifacts, wayfinders combine the function of a mundane compass with magical utility and—a somewhat guarded secret—the power to enhance the function of ioun stones. Within each wayfinder is a fine lattice of wire, spun of silver, gold, or even more precious metals. This lattice channels and amplifies the natural energy of the ioun stone, extending its benefits to the owner as long as the wayfinder is held or kept close to the body. Inserting or removing an ioun stone is a standard action that provokes attacks of opportunity. Some wayfinders have multiple slots for ioun stones; these usually—but not always—function independently (an enhanced power from the first slot has nothing to do with the enhanced power of the second slot, whether or not another stone is present).
Though any spellcaster with the proper ability can create a new wayfinder, most are decades or centuries old, passed down from mentor to student or through family lines.
