Damage 2.0

Blast b Blast Damage is one of the six secondary elemental damage types, composed of Cold b Cold and Heat b Heat elements. The violent force of this damage is highly destructive to Grineer machinery and brittle fossilized Infested creatures, but performs poorly against the Ferrite Armor worn by many Grineer units.

The Blast b Blast status effect is an explosive knockdown (as opposed to Impact b Impact's knockback), stunning all enemies with 5m of the target. This effect can be applied against recovering victims, causing them to flip in their recovery as if they were normally stunned. The corpses of victims killed by Blast b Blast damage will be launched away from their initial positions. Against Tenno, the visuals of the status effect will last two seconds. Note that the Blast b Blast proc does not cause damage to multiple targets, it knocks down nearby enemies with the damage shown as 0 to shields, even on non-shielded enemies like the Grineer. An enemy killed by a Blast b Blast proc will be quickly disintegrated.

Corrosive b Corrosive Damage is one of the six secondary elemental damage types, composed of Electricity b Electricity and Toxin b Toxin damage. It is immensely useful against most Grineer troops and heavyweight Infested creatures, but fares poorly against the Proto Shields of some Elite Corpus enemies.

Corrosive damage's unique status effect is Corrosion, which permanently degrades the target's current armor by 25%. The damage of the corroding shot is applied after the Corrosive b Corrosive proc reduces the armor. Corrosion can be applied multiple times to the same target, with each following proc reducing the remaining armor by another 25% of its current (not the initial) value, thereby causing the target's armor to decay exponentially. Against Tenno, the status effect lasts for 8 seconds. In the case of shots with multiple pellets (both by default and through multishot mods), multiple stacks of Corrosion can be applied in the same shot. The enemy corroded by the proc will be covered in a green, electricity-like substance.

Corrosive effects do not remove hard invulnerability effects, such as the special protection possessed during the first half of the fight with Lieutenant Lech Kril. Additionally, a few bosses (notably Vay Hek), seem to be immune to heavy Corrosion-stacking.

Gas b Gas Damage is one of the six secondary elemental damage types, composed of Heat b Heat and Toxin b Toxin elements. It is particularly effective against light Infested types, but deals lower damage to Grineer and Corpus bodies.

Gas b Gas damage's status effect is Poison Cloud, which applies a Toxin b Toxin Poison effect to all enemies within 5m of the struck enemy. Poison deals 125% of your weapon physical + Poison damage or power's base damage per tick (9 ticks in 8 seconds) as Toxin b Toxin damage.

To be clear, Gas b Gas Damage has 3 different damages :

   Gas b Gas Damage & Proc is single target (Sum of all damage on arsenal +/- resistance)
   Toxin b Toxin Damage & Proc to all enemies within 5m (Sum of physical damage + Toxin)
   1st Tick of Toxin b Toxin DoT that deals 125% of the previous Toxin damage.

Gas b Gas damage isnt directly linked to Toxin b Toxin damage & DoT. And it is recommanded to use a single Heat b Heat mod and 2 Toxin b Toxin mods to get more damage from this damage type.

Multiple instances of the effect can stack on the same target for increased damage over time. Because the damage from this status effect is Toxin b Toxin, not Gas b Gas, it can bypass shields and compensate for the damage penalty against Grineer and Corpus organics while not adding much more against the Infested.

Magnetic b Magnetic Damage is one of the six secondary elemental damage types, composed of Cold b Cold and Electricity b Electricity elements. It is very effective at taking down Corpus Shields, but is heavily mitigated by the Alloy Armor worn by many higher-level Grineer units.

The Magnetic b Magnetic status effect is Disrupt, which reduces the target's current shields and maximum shield capacity by 75% over a duration of 4 seconds. The damage of the disrupting shot is applied before the Magnetic b Magnetic proc reduces the shield. After the effect expires, the target's current and maximum shields will be restored while damage done during the proc translates directly onto the current shields. Should another Magnetic b Magnetic status effect occur while one is already active, the duration will be extended and the target's current shields will be permanently reduced when the effect expires with the second proc doing its damage again.
Affected Tenno suffer additional effects: their HUDs will be disrupted, 100% of their energy will be drained, and they cannot gain energy until the proc ends. Magnetic b Magnetic procs will show blue rings matching the shape of the affected target moving from top to bottom.

Radiation b Radiation Damage is one of the six secondary elemental damage types, composed of Electricity b Electricity and Heat b Heat elements. It is highly effective against the Alloy Armor worn by many high-level Grineer units but is penalized against most Corpus Shields as well as most Infested foes.

This damage can cause the Confusion status effect. Affected enemies target, and can be targeted by, their allies for 12 seconds. It is similar to Nyx's Chaos ability. Passive auras, like those from Eximus units or Ancient Healers, stop affecting other units while their sources are Confused. Enemies that are linked to an Ancient Healer can be inflicted with Confusion, which will cause the Ancient Healer to also be affected by this proc, which, in turn, cuts the link. Radiation b Radiation procs look similar to Electricity b Electricity procs, but the color is greenish blue instead.

Against Tenno, the effect lasts for 4 seconds and reduces their weapon accuracy while allowing the player to cause and receive friendly fire. An irradiated Tenno cannot revive fallen allies, including Operatives in Rescue and Sortie Defense missions, even if the process started before the proc, in which case it will be interrupted. Self-damage cannot cause Confusion. However, an irradiated Tenno can inflict Confusion on another ally by attacking them with an ability or weapon that procs Radiation.

Viral b Viral Damage is one of the six secondary elemental damage types, composed of Cold b Cold and Toxin b Toxin elements. It deals increased damage against IconGrineerBGrineer and IconCorpusBCorpus bodies, but reduced damage to most light Infestation bInfested foes.

The Viral b 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[1] the Viral b Viral proc reduces the health. Multiple procs do not reduce the health further, but only serve to refresh the time spent with halved health. Damage done during a Viral b Viral proc translates directly onto the health after it expires.

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 b Viral consistent in both PvP (Conclave and Duels) and PvE.
