Key of Veles
Wondrous Item, requires attunement
A key of Veles is a corroded, copper-and-mithral key about 1 foot long. When held near a ley line or shadow road, it automatically points toward that line or road and permits the holder to access the ley line’s effects as a spellcaster. If the holder speaks the command word, it opens that’s line’s shadow road. Each such use expends one of its 10 charges.
After a key of Veles is used 10 times, it cracks and becomes useless. The device also opens doors, chests, gates, bars, shackles, chains, and bolts, and it automatically dispels an arcane lock cast by a wizard of lower than 15th level. This expends no charges.
