Ok, I mean that Tashi spend his present action moving and then another action confirm the guard is there. He would not make full body touching, just confirm there is body laying in the ground and he traces hand close to ground then mid air to make a sweep to discover the body.<br/><br/>In next turn Tashi grabs the guard (I assume free action to take hold of something) and then use full round action for full retreat mode where he uses extreme effort to get +4 to his Str score for feats of strenght. So if Shiro is still on guard when he does it, he may get knocked over to his ass as suddenly guard surges underneath him forward like launched to somewhere :P. But if it is move action to take grab, it just means he only moves 40'ft or so when he moves off the cloud (and he gets 1 round exposure to the gas and needs make another fort save.....or no fort save as he made one already vs the cloud).
