Other Information[edit]

Enemy Attack down effect
Attack is reduced by 20%.

Dia / Bio Priority[edit]

Dia and Bio will stack if cast in the right order:
Bio III > Dia III > Bio II > Dia II > Bio > Dia
Any "greater" magic will always overwrite the "lesser" one despite time it was cast.
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. However, if Bio II is cast, followed by Dia II, both will remain in effect.
Note: This is not necessarily the case for player characters who have been hit with both spells.
Duration is only affected by the level of Bio III's current merits.
Level 1: 30 > Level 2: 60 > Level 3: 90 > Level 4: 120 > Level 5: 150
