The domain of change is broad, probably even broader then the domain of magic, and as a result of its widespread functionality, it is very unfocused and weak in comparison to other focused domains.
As such if the domain of change and any other domain were to clash over the manipulation of something, the domain of change will almost always lose unless that something doesn't fall within the opposing domain. Even the domain of magic would win against the domain of change if it set off a spell to mess with the same thing.
As such if she and another god are trying to mess with the something, she would no doubt lose every time, as her widespread functionality would pale in comparison to a god focused on a specific thing, much like magic is. Funny enough, she'd probably even lose to magic if it set off a spell that would manipulate what she's messing with. Though because of this, the inverse is true should that something fall outside of the other god's domain.
Rules and limits of the change domain:
1. Before there can be change,
* there has to be something to change,
* one must understand what it is they are trying to change,
* and one must understand the change itself, lest a random change be the result.
2. The better understood something is, the more easily one can cause specific and/or more challenging changes. As such,
* one who understands many things on a simple level will be able to cause many simple changes,
* while one who understands a single thing deeply will be able to change that single thing in many ways.
3. It gets exponentially harder to cause change the more powerful and/or complex something is. As such,
* to reverse a change costs one twice as much as it would to cause that change,
* changing things on a large scale will tire one greatly.
* trying to change something of another god's making without their help will wipe one for a while, regardless of if it worked. (No mortal should try this, as it might cost them their life.)
* one cannot cause change to the psyche or mind, as it is too complex.
* one cannot cause change to energy except for diverting its path slightly, as it is too powerful.
* one cannot cause change to divine cords, and by extension gods, for they are
far too powerful.
4. Though the domain of change has a widespread athority on many things, it will lose its control over something for the duration of its encounter with any who have a greater and more specialized athority over that something.
5. If something is of direct relation to oneself, like one's body or clothes, one will find find it somewhat easier to cause change to such things, though such things must truely be theirs for this to be of effect.
