None of those three, if not count low-light vision or darkvision for anything. Also I have 6 reserve chakra left; any spending I am fatiqued on spot and be long time off from any actions. I have super hearing technique but no time to apply nor chakra.<br/><br/>Usual smoke screens provide concealment past 5'ft but if your in 5'ft you should only get partial concealment. That way Tashi could have idea of Shiro's position and do bull rush on him as his standard action after moving to spot where body was. Otherwise his second action after moving is just check body is there and next round he grips and then moves.
