"Will take big bio damage every turn. Anyone on the field can be randomly infected between turns."

Virus icon, EBF5

Virus is a negative status effect introduced in Epic Battle Fantasy 5. It is associated with the Bio element, and its icon is a purple blob lined with a faint green glow. It deals Bio-elemental magical damage to the victim, and can spread from one character to another regardless of what side they are on. Unlike most status conditions (but similar to Poison from the first three EBF games), Virus stacks don't tick down at the end of each turn.

Epic Battle Fantasy 5

Virus deals magical Bio-elemental damage that is twice as strong as Poison's (ie, MaxHP * Hit2HP * 0.0012 * Virus tier) at the end of the afflicted side's turn.

  • If any foe or player (including backup players) is inflicted with Virus at the end of their side's turn, each active player/foe has a chance of getting inflicted with 1x Virus; the spread chances are:
    • If a foe is inflicted with Virus
      • Each foe has a 30% chance of getting inflicted.
      • Each player has a 10% chance of getting inflicted.
      • If the foe has a catch score equal or lower than 4 (ie, most bosses and mini-bosses), both spread chances are tripled, becoming 90% chance for foes and 30% chance for players to get inflicted.
    • If a player is inflicted with Virus
      • Each foe has a 20% chance of getting inflicted.
      • Each player has a 40% chance of getting inflicted.
  • Since Virus' damage is Bio-elemental, it'll deal 1.5x damage if the target also has Tired at the end of the turn, and unlike regular attacks, this won't consume Tired stacks. By the same token, since Virus deals magic damage, its damage will be doubled by Invisible and nullified by Enchanted.
  • Virus can score a critical hit (for 1.5x damage), but only with help of the Stagger status effect, this won't consume Stagger stacks.
  • Virus' damage has the second lowest priority amongst damaging statuses, with only Doom taking place after it.
  • Like Poison, Virus will not cause any damage when the victim is Frozen, but can still spread from a frozen player/foe.
  • If the last foe in a wave dies to Virus, when the next wave of foes comes in, the player will have the first turn.
  • As with most other damaging statuses, Virus' "attack" has permanent 999.99 Accuracy, not affected by anything. Thus, there is a chance to dodge it if victim's Evade is above that value.
  • Like most other damaging statuses, Virus' damage is reduced in Easy and Zero difficulties (down to 70% and 35% respectively) for both players and foes.
