Tail sweep is an ability practiced by several creatures, including the cave lizard, three-toed tegu, and snow madrinol. The maneuver is fairly self descriptive; the creature spins around and attempts to knock you over with their tail. Usually, this maneuver is easily avoided, even by pures, but when successful, will prone the individual and inflict anywhere from 3 to 20 RT when successful. The cave lizard is capable of performing a standard attack immediately after using tail sweep, making it more dangerous in that they are guaranteed a chance to take advantage of the target's prone DS, even if the RT is only 3 seconds.
This ability resolves with a visible standard maneuver roll (SMRv2).
