Silver Ladder Rote: Solomon’s Sight
King Solomon was said to be wise in the ways of magic, a master of the spiritual realms. This rote allows a Ladder willworker to emulate that ancient ruler, perceiving the most intricate and delicate nuances of magic, and the local complexion of the barrier holding spirit apart from flesh. Mages of all orders use this rote, but Mysterium willworkers often do so under urgent circumstances (Wits + Occult + Spirit).
