Other Information

Diaga gives Dia effect.
April 3, 2019 Version Update
"The defense down effect of the white magic spell Dia has been adjusted. Numbers in parenthesis represent the value when affected by the Corsair ability Light Shot.
Name Pre-adjustment → Post-adjustment
Dia 5% → 10%(13%)
Dia II 10% → 15%(18%)
Dia III 15% → 20%(23%)
Diaga 5% → 10%(13%)"
Dia / Bio Priority 
Dia and Bio do not stack. Since Light and Dark are in opposition, whichever spell is higher level (requires a higher level job to use), overwrites the other.
Dia < Bio < Dia II < Bio II < Dia III < Bio III
Any "greater" magic will always overwrite the "lesser" one despite the time of casting.
Note: This is not necessarily the case for player characters who have been hit with both spells.
