[@Tyler] My idea was that they can make objects do anything that a normal person would be able to do with them. There are no special properties of any kind given to objects simply because they are affected by the power. For sake of example a torch could be commanded to light itself on fire but wouldn't be able to unless an ordinary person would be able to see or sense fire or another method of setting itself on fire and the torch is able to reach the fire. Another thing I've thought of that would fit into this example would be that if an object is split into multiple parts each part will attempt to complete the order if able. However, each part counts as a different object for the "number" of objects being controlled. This also applies regardless of the size of the pieces. Going back to the torch example, if they told the torch to float across a room, set itself on fire and then return on the return trip each flake of ash from the torch would count as a separate object. This means that as the torch returned to the character it would start to slow down, then eventually start to fall although when it hit the ground it would continue to roll (Each piece of ash is effected by the same amount of force as the entire torch is, meaning that the flakes would still be floating toward the character). Eventually there would be enough ash that the power would fade. This would also effect any other objects that were being controlled at the same time. By this principal fluids or items that are partially fluid (such as a melting steel bar) would be unable to be controlled for any period of time (I'm also going to count clothes and other fabrics to a lesser extent in this too or else it would be far too OP to simply tell someone's clothes to crush them). Also, inanimate objects are dumb and a stickler for definitions. If a chair is supposed to "not let anyone sit on it" then someone could still use it as a footrest or lie on it. Before there are any arguments about the interpretation of orders, I think it would be best that the reasonable interpretation (as determined by the DMs) which is least beneficial to the character with the power should be used. The rule about contact is also strict, they are not able to simply unlock doors by touching the knob as they are not actually touching the components of the lock. They are able however to force the knob to turn and maybe break the knob or lock. Similarly turning a gun into a floating sentry would require two different orders, one to make the casing of the gun hover and point at people, another to make the trigger pull itself. This power lacks a single definitive weakness but I think the limitations I've outlined above are reasonable and allow for a multitude of different ways to overcome "dominated" objects.
