Instead of controlling his entire surroundings, she was telling him to change the surrounding condition to produce the effects he wanted. Kind of like having a fan to create airflow. Eldrian didn't need to make the wind if he could make a fan.
Now, depending on the type of magic Eldrian wanted, this could be simple or highly complicated. And there was a little problem:
It was challenging to know when mana was being converted to what he wanted or when it was only supporting the reactions he aimed for.
Because of mana's ability to change form and become anything, it was pretty easy for it to take the form Eldrian was envisioning.
This was not a problem that normal mages fell into. They relied on spell modules to guide them. But, since Eldrian often forced the issue, mana filled the gaps in his knowledge.
This meant more mana needed to be expended for the same spell. Which honestly wasn't much of a problem for Eldrian.
