Hot potato coming up again. AFAIK Symbios are; Activates upon ARM/BTS roll provoking attacks. Gives the user Total Immunity at that single order, ARM 9/BTS 9. Fine if you gets shot by a bullet. But if the attacker uses Flash special ammo, Flash Ammo is detailed as; Roll After a successful Attack using Flash Special Ammunition, the target must make a BTS Roll. So flash triggers BTS roll. Symbios are off when the owner make a BTS roll. Flash is nominated as 'Attack'. Does this make Symbiomate active to Flash Pulses?
