What is the Viral Shot? (The TL;DR Version) In Fatal Bullet , the Viral Shot is a Debuff Skill exclusive to the Sniper Rifle weapon class. Unlike standard shots that simply deal damage, the Viral Shot is a projectile that inflicts a double status effect on enemies:
Power Down (ATK Debuff): Significantly reduces the enemy’s physical and optical attack damage. Armor Break (DEF Debuff): Significantly reduces the enemy’s physical and optical defense.
Essentially, this one bullet makes you take less damage while dealing significantly more damage. In the post-game DLC dungeons (Dissonance of the Nexus, Collapse of Balance), bosses can one-shot tank builds.
