Other Information

Enemy Attack down effect
Attack is reduced by 27/512 (5.27%)
Dia / Bio Priority 
Casting Bio of the same tier as its Dia counterpart will result in the Dia status being removed (Dia and Bio do not stack). Example: If Dia is cast, and Bio is cast afterwards, Dia will be overwritten. If Dia II is then cast, Bio will be overwritten. If Bio II is cast, Dia II will be overwritten.
Bio III > Dia III > Bio II > Dia II > Bio > Dia

Application

  • Use of Dia in a party should be balanced with the use of Bio as Bio will overwrite Dia, but Dia will not overwrite Bio. Dia should generally be used on high-defense mobs such as Crab.
  • Use of Bio in Campaign Battles counts toward Elemental Magic Damage in terms of rewards calculation, despite its primary use being that of enfeebling. The reward is based solely on the initial damage reported in the log, and not on the overall damage-over-time.
