Gameplay

Upon executing Eukrasia, Diagnosis will change to this action. After using it or other Eukrasian actions, it will revert back to Diagnosis.
The basic barrier granted from this action, Eukrasian Diagnosis cannot be stacked with from scholar's barrier spells – Adloquium and Succor / Concitation / Accession. Barriers from sage's barrier spells will instead overwrite Galvanize entirely, due to the barrier consumption priority system. Eukrasian Diagnosis will, however, stack with other barrier ability actions from scholar (i.e. Consolation) or any other barriers from other jobs (i.e. Divine Veil).
When this action is critically applied ("When critical HP is restored" in the tooltip), it will also apply Differential Diagnosis , an additional, separate barrier with the same potency of Eukrasian Diagnosis. Differential Diagnosis will not be overwritten by, and can be stacked with scholar's barrier spells.
