Easy Way To Kill A Tough Opponent:

This is an easy way to kill a really tough Opponent. For example Umbra. The way to do this is:

First: if your a master at sneak (not complete master)it will be easier.
Second: You also need to have the sign of the Lover.

To do this sneak up behind them and use the Lover's Kiss. Then unleash your series of sneak attacks doing times whatever damage you do until the enemy is dead or the Lover's Kiss effect expires (at this point you have no sneak skills). This can be done to anyone and makes a great way to kill someone such as a guard alone. It is also great to use the Lover's Kiss to paralyze an opponent to make a great get away.
