Birth lover
The birthsign of the Lover gives the player the Lover's Kiss power once a day to paralyze an opponent for 10 seconds at the cost of 120 points of Fatigue.

(Summary and picture from Official Elder Scrolls Site)


Lovers Kiss can make a useful emergency tool to escape a foe, for example to regain Magicka, Fatigue (Potions are recommended) and/or Health. The Illusion spell is better suited to the job, without the cost of fatigue.
