I have Smoke Flash, and I've been trying to find the best way to use it... and to be frankly, I simply can't! Most of the times the mobs still come running after me... the Smoke Flash is NOT interruptable. U can even run while doin it... I still need it to test it some more, but let me tell u right away, that something is wrong with it... it's pretty much useless! In about 10 situations, only once I managed to placate the enemies... and you don't get hiden... Besides, if you ARE Hiden, and use it, you'll come out of Hide...
I donno, let me tell u, that if I don't find really soon the magic book of "How to work with Smoke Flash", then I'll just put it aside... I'm really disapointed at it!
