Where something would have been met with violence, it's now met with judgement.12. Continuing from above, Aster's body becomes several times tougher while under Partial Manifestation, making it much harder to damage.13. Even at rest, she does not stop working. Unless directly ordered to, it is unlikely that there is not some magical formula being created and refined at any given moment.14.
