Dia is an Enfeebling Magic spell that can be cast by low - level Red Mages and White Mages . It deals a very small amount of light - elemental damage and applies a status effect that reduces the target ' s Defense and deals one point of additional light damage per tick over the course of a minute . The higher - level Diaga offers the same effect against multiple targets while Dia II and Dia III are altogether more powerful . Some monsters wield group - cast versions of these spells which are not available to players . The use of Dia conflicts with the use of Bio such that only one of the two may be active on an enemy at a time . Bio prevents Dia spells of equal or lower rank from being applied and dispels them if they are already present on a target . Though higher tiers of Dia can overwrite Bio in return , such as Dia III replacing Bio II , Bio ' s strongest form is ultimately insurmountable in this fashion . Monsters are sometimes able to inflict both Dia and Bio upon players , however . Adventurers who choose Red Mage as their first job are given a free Dia scroll .

Etymology . In the original Japanese release of " Final Fantasy " , " Dia " was an abbreviation for " Dispel Undead " , as the " u " is written as an " a " in that language . When it was later realized that " Dia " and " Día " mean " day " in Portuguese and Spanish , the name was applied to other localization as a play on the idea that sunlight is harmful to the undead .
