While this spell is in effect, you are able to repeatedly teleport a very short distance. During the duration of this spell, any time you are in melee with another creature, you are instantly teleported right behind and facing your opponent just before you take any actions for the round (such as attacking, spellcasting, moving, etc.). This enables each of your attacks to gain the benefits of flanking (gaining a +2 to attack rolls and possibly allowing sneak attacks).

You only teleport once per round, and always at the start of your actions. You gain no protection from this spell, as it is simple for your opponent to pivot and attack you on his own action. If, at the start of your actions for a round, there are no opponents within 5 feet (the distance you could immediately attack from with a melee attack), you do not teleport that round.
