Osteomancer's Pouch

ITEM 8
Price 480 gp
Usage held in 1 hand
Bulk —

This leather pouch holds a pair of six-sided dice carved from actual knucklebones. When rolled, the dice grant you a vision of a distant location, though their power is unreliable.

Activate—Roll the Bones (concentrate, manipulate)
Frequency once per day

Effect You roll the dice. If you roll two 1s, the activation fails with no effect. Otherwise, the dice cast Clairvoyance for you. When cast in this way, the spell's range becomes 100 feet × the result of your roll.
