Status Effect[]


The status effect of Viral DamageDmgViralSmall64.png Viral damage is Virus. It amplifies damage to the health of the afflicted target by 100% for 6 seconds. Subsequent procs add 25% increased damage to health up to 325% in total after 10 stacks, with each proc having their own duration. This effect will work even when the health is protected by armor ("yellow health"). Only the shield is not affected.

Calculating resultant damage if at least one Viral proc is on target. Damage Vulnerability provided by Viral procs are multiplicative with other damage bonuses.

For status effects that apply damage over time (e.g. Slash DamageDmgSlashSmall64.png Slash, Toxin DamageDmgToxinSmall64.png Toxin, Heat DamageDmgHeatSmall64.png Heat, Gas DamageDmgGasSmall64.png Gas), the damage dealt by the proc throughout its duration is calculated based on whether or not a Viral DamageDmgViralSmall64.png Viral proc is active when the DoT tick deals damage. For example, a weapon with 100 damage that applies a Slash DamageDmgSlashSmall64.png Slash proc, if the target has 1 Viral DamageDmgViralSmall64.png Viral proc, will deal 200 damage, then 70 damage per second from DmgSlashSmall64.pngBleed until the Viral DamageDmgViralSmall64.png Viral effect ends, when it will go down to 35 per second. If the target does not have a Viral DamageDmgViralSmall64.png Viral proc initially, the DmgSlashSmall64.pngBleed damage will be 35 per second until the target takes a Viral DamageDmgViralSmall64.png Viral proc, which will then multiply the DoT accordingly to 70 per second. This means that the multiplier is not applied twice to DoTs, unlike faction damage multipliers.

Enemies afflicted by a Viral DamageDmgViralSmall64.png Viral proc are coated in a flowing, leaking miasma of the Energy color of the weapon that inflicted it.


Viral DamageDmgViralSmall64.png Viral does not have a Railjack space counterpart and is thus not able to proc any status effect nor is it included in calculations for status proc weighting.
