Kingdom Hearts 3 Magic
In Kingdom Hearts 3, magic seems to have two casting options, magic performed outside of free run, which is similar to previous titles and magic performed during free run. Similar to Final Fantasy XV, Free run is activated by running. While running or in free run casting a spell activates a type of motion based magic while standing still or being in mid-air will cast standard magic. Below are examples of magic confirmed for Kingdom Hearts 3 along with examples of standard and free run magic. Note: This is speculation, but likely the case.
Fire Magic
Fire Magic + Free Run
Aero Magic
Aero Magic + Free Run
Cure Magic
Cure was on the shortcut menu in the Jump Festa 2015 trailer alongside Fire, Blizzard, and Aero.
Water Magic
Water Magic isn’t confirmed, but the enemies in Kingdom Hearts 3 use water-based attacks. It is likely that Sora will be able to cast Water Magic in Kingdom Hearts 3. Note: Water based stats such as Water Resistance and attacks were officially introduced in Kingdom Hearts 3D: Dream Drop Distance. Sora was not able to use water magic but his Dream Eaters could use water based attacks.
