Shadow Advance

Description	Uses smoke to hide self in order to assassinate the enemy. Effect cancelled after initiating attack.
Notes	Because it wears off almost as soon as you initiate the skill, you will not have the attack bonus on all but the quickest of skills you use. Due to the way damage is calculated, the increase in attack does not always translate to a proportional increase in damage. Similarly, you will only have this effect for one normal attack, but it will have the full bonus. The effect will end early upon switching weapons.
