Bio Virus
- "Probably not a good idea to keep this in your pocket."
- ―In-game description, Epic Battle Fantasy 4 & 5
Bio Virus is a crafting item in Epic Battle Fantasy 4 and 5. It is used for forging mostly Bio-related equipment.
In EBF4, the Bio Virus resembles a single green micro-organism, presumably some sort of virulent bacterium. It can be bought in Whitefall Town and Goldenbrick Resort for 3,000 gold, and 68 are needed to upgrade everything; the vast majority will be used for the Destroyer.
In EBF5, the Bio Virus is a round glass bottle partly filled with bright green liquid and stopped with a brown cork. It can be bought in Greenwood Village, Mystic Woods, The Great Sea, and Redpine Town for 3,200 gold. 96 are needed for the relevant upgrades.
Drop Rate
Bio Viruses are mostly dropped by Bio-affinity foes; notably, the Sand Worm is guaranteed to drop one in both of the games where the Material appears.
