The Ignis is a Grineer flamethrower used by Grineer Scorch and Hyekka Masters, unlockable through Chem Lab Research in the Dojo. The Ignis releases a long reaching continuous spray of flames in a frontal cone, thus making it exceptionally useful for handling large crowds, albeit at the cost of high ammo usage and a fixed range.
Deals Heat damage, which can create combination elements when combined with other elemental mods, such as Cold. However, it will no longer deal the original fire damage, losing its high bonus versus Light Infested (+50%). Thus, it is advised to add Toxin damage to create Gas damage to kill Light Infested. Add Electricity + Toxin to create Corrosive damage, and add Cold to create Blast damage to kill Heavy Infested.
It is a wise idea to equip a long-ranged weapon in your secondary slot when using the Ignis.
It is unwise to have Specters equip this gun as they only fire on targets when they are ~10m away from them.
The AoE of the Ignis is treated as Punch Through due to the flames being considered explosions.
Firestorm gives the Ignis' damage cone a greater area of effect, up to a +24% increase.
Combustion Beam can also be equipped to the Ignis, causing enemies to deal damage on death to other nearby enemies. This aids in crowd control and quicker elimination of weaker and closely-grouped enemies.
Sinister Reach can also be equipped on the Ignis, greatly increasing its effective range, while visually reducing the radius.
Due to its nature of AoE, this weapon is particularly effective against destructible projectiles.
Adding Heavy Caliber as a second Serration results in an increase of damage. The reduction of accuracy, which is a negative for most weapons, is arguably a benefit for the Ignis as the AoE spread will widen slightly.
This will however make headshots more difficult to land.
Ignis starts its damage on a small radius from its barrel spanning about 1 meter, which explains the damage being dealt on enemies around the user and not directly. This can be taken advantage against melee units, especially the Infested.
The Ignis is designed to deal with crowds, spreading low damage but hitting all enemies in range, where most other weapons (besides explosive dealing AoE weapons) are single or multi-target. In other words, the larger the crowd, the better the weapon becomes at distributing damage compared to most other weapons.
The Ignis is very useful in reactor core Sabotage missions, as its punch-through and wide attack area allows it to destroy several exposed reactor cores at once.
Oddly it wasn't just the appearance, as the update that changed the model and reload animation of the Ignis made the Grakata reload as if it was the Ignis.
The Ignis was first shown in the developer Livestream #5.
The volume of fuel the Ignis carries would be impossible in the real world using today's technology, as the duration of continuous fire of the entire magazine lasts far longer than actual flamethrowers. This implies that the fuel used (possibly derived from Detonite) is extremely efficient.
The front portion of the barrel heats up through continuous firing of the weapon, visible after roughly 25 units of ammo has been expended.
Changing the default Heat damage of the Ignis modifies the visual effects of the flame released depending on the new element: Blast damage causes the barrel to emit sparks, Radiation damage generates bolts of electricity within the flame, and Gas damage changes the flame into a thick cloud.
In earlier builds, this change overrode any color customizations to the Ignis' flame color.
