Bio II is a Dark Black Magic spell from Final Fantasy XI. It is the second tier of the single target Bio spells.

Obtained[]

Bio II can be learned by Black Mages, Red Mages, and Dark Knights. Bio II's scroll can be bought from venders in either Windurst Waters, Selbina, or Aht Urhgan Whitegate. In addition, it can also be obtained from other players via the Auction House or Bazaars.

Puppetmaster Automatons can learn the ability at level 36 and have a Magic Skill of 107.

Use[]

Bio II is a Dark Magic ability that deals gradual Dark damage and weakens the afflicted target's physical attacks. The rate of damage, the duration, and the attack stat reduction are all improved over the original Bio spell. The Bio status can be cured with Erase, Esuna, Exuviation, or numerous items, but not by Poisona or Antidotes.

Bio II will overwrite the effects of Dia and Dia II, but can be overwritten by Dia III.
