where "Level" is the caster's current level and "Magical Attack" is their Magic atk stat. This is effectively 1.3125x the base magic damage.
Bio2 can be used by characters with the Poison Materia at level 2. The spell deals a decent amount of Poison-elemental damage, and has a 48% chance of inflicting the Poison status. If inflicted, this status deals physical Poison-elemental damage equivalent to 1/32 of the target's max HP every 2.5 units of time, ignoring Defense and Barrier. However, Bio2 has a considerable MP cost while not improving the chance to inflict the status compared to the basic Bio spell. This means it is not economical to use outside of against bosses weak to the Poison element.
Bio2 can be amplified by pairing the Poison Materia with Support Materia. Using MP Absorb can mitigate the high MP cost, while All can spread its damage across all enemies, and also gives the chance to inflict multiple targets with Poison. Nonetheless, its best use is against large targets that are weak to Poison, meaning that the MP Turbo or Quadra Magic spells are useful to amplify its strength against single targets.
