With regular teleport skill, you can face aby direction and you will tele to where mouse pointer is. With tele enchant, you have to be facing the direction you want to tele to or the tele will just move you further in the direction you are facing.
Also, the tele enchant forces you to move a minimum distance. Not sure if bug or not, but i can no longer tele just a small bit to the left or right with tele enchant
