So how useful is it to be able to use a standard action to teleport party members via Hex Vulnerability and Leap of Heavens?
Heaven's Leap (Su): The shaman is adept at creating tiny tears in the fabric of space, and temporarily stitching them together to reach other locations through a limited, one-way wormhole. As a standard action, the shaman can designate herself or a single ally that she can see who is within 30 feet of her. She can move that creature as if it were subject to jester's jaunt. Once targeted by this hex, the ally cannot be the target of this hex again for 24 hours.
That could be useful for trying to avoid climb/acrobatics checks. In combat it would be useful on a rogue or someone with sneak attack to re-stealth.
