Well, for how long are they destroyed? It only seems fair it should be the same for commanding.Good clerics destroy, evil command. But for how long, 10 rounds or permanent?
A commanded creature is under themental control of the rebuking creature. The controller must take a standard action to give mental orders to the commanded creature. At any one time, the controller can command any number of creatures whose combined Hit Dice don't exceed his level. The controller can voluntarily relinquish power over any commanded creature to command new ones. Otherwise, the commanded state is permananet.
Turning has a range of 60 feet, but affects the closest turnable creature first. You don't need line of sight to a target, but you do need line of effect. You can skip over creatures that have previously been turned but are still within range, so that you don't waster your turning capacity on them.
