Jar of Shifting Sands

ITEM 7
Price 320 gp
Usage held in 2 hands
Bulk L

This small, ceramic jar is full, holding approximately a quarter gallon of sand. When poured out, the jar immediately begins to conjure more sand. It is said, however improbably, that one of these jars is responsible for creating at least one desert in the world.


Activate—Avalanche of Sand (manipulate)
Effect You cause sand to pour out of the jar at a rate of 1 gallon per round. This doesn't end until the cap is placed back on the jar as an Interact action.

Activate—Spill Sand (concentrate, manipulate)
Effect You quickly pour sand over an adjacent square, making it difficult terrain. You can't use either of the jar's activations for 1 minute.
