Viral Damage is one of the six secondary elemental damage types, composed of Cold and Toxin elements. It deals increased damage against Grineer and Corpus bodies, but reduced damage to most light Infested foes.
The Viral status effect is Virus, which reduces a target's current and maximum health to 50% for 6 seconds. The damage of the infecting shot is applied before the Viral proc reduces the health. Multiple procs do not reduce the health further, but only serve to refresh the time spent with halved health.
As of Update 17.2, the health lost by any type of enemy due to the proc is restored after the effect ends, thus making Viral consistent in both PvP (Conclave and Duels) and PvE. Consider the following examples:
|1 Proc, 50 Viral Damage||2 Procs (within 6 seconds), 50 Viral Damage (each)|
|Grineer Health||Viral Modifier||Corpus Health||Viral Modifier||Infested Health||Viral Modifier|
|Ferrite Armor||Shield||Infested Flesh|
|Alloy Armor||Proto Shield||Fossilized|
|Offense||Critical Hit • Damage • Enemy Body Parts • Multishot • Punch Through|
|Defense||Armor • Health • Shield|
|Physical||Impact • Puncture • Slash|
|Elemental||Cold • Electricity • Heat • Toxin|
|Combined||Blast • Corrosive • Gas • Magnetic • Radiation • Viral|
|Unique||Finishing • Void|
