So if a character is under the effects of Smoke Veil and they recast the ability, this has the effect of canceling the current Smoke Veil buff rather than refreshing it.  

 

This becomes a problem with Slippers of the Assassin in the case of killing multiple targets at once using an AoE such as Fireball.  The deaths seem to occur at the same time in terms of evaluation, resulting in the buff canceling itself out after the first kill.  Thus killing 2+ enemies with an AoE causes the effect to fire, but my character is now quite visible in the face of multiple singed and angry enemies.

 

Not sure if this kind of behavior is intended?
