torrent snare duration

[pavaan]

What would be torrent snare's duration. It does not state how long the difficult terrain it creates lasts. Until the end of the turn of who ever triggered it. One full round, or something else?

It turns the ground slippery with wet plants. I guess the terrain will be difficult til it's cleaned up or the area dries up. But the first one who triggers it will be so surprised and slips and falls prone if they don't pass the Reflex save.

It's permanent, or permanent until someone cleans it up or something else happens.

The save effect is only for the creature who triggers the snare, not anyone who comes by the difficult terrain later.
