Ah the same as using magic in a physical contest. As Lucius said, it's a pretty straightforward way of fighting. Though Vesta doesn't enjoy close quarter combat and will simply keep herself away from it.
She showed off a few counters against Aleph (e.g. setting up walls to prevent his advance, removing the ground from underneath him and making the ground ripple outwards). Let alone she kills Demon Beasts for a living mostly.
Other counters could be as Lucius said, rock armour, removing the ground from underneath Vesta herself (e.g. going underground), creating a dome around of herself, etc. She does have physical spells as well you know. (To what they are should be rather obvious)
Let alone perhaps shooting rocks if he gets too close. Who's to say Vesta doesn't keep a pocket full of pebbles for such a situation?
Lots of counters I can think of.
