Also added this paragraph to the Setting in regards to mana:

There are 2 methods of using mana, manipulation and casting. Manipulation is directly controlling the elements in one's surrounding environment. This is limited by line of sight and the availability of whatever the mage can skilfully control, but is quicker and generally less taxing to use. Casting on the other hand involves the conversion of raw magical energy into matter to conjure something from nothing. Useful for when resources are limited or unavailable, but the feedback is more burdensome on the mage as manipulation is still required after casting, essentially doubling the cost of power involved.

Thanks to [@ReusableSword] for the idea.
