See the user build section for builds using this weapon.
Hellfire and Wildfire apply fire elemental mod damage to the weapon. They do not act like base damage mods (but stack with the innate Heat damage of the weapon.
Adding Corrosive / Magnetic in addition to heat damage makes the Ignis very effective versus Grineer / Corpus
Ignis can be effectively used to kill enemies on catwalks/stairs above the player without having line of sight to them on missions like Xini.
It is a wise idea to equip a long-ranged weapon in your secondary slot when using the Ignis.
One of the main disadvantages to the Ignis is its short range, which can potentially place you in unfavorable situations. Consider equipping this weapon on a durable Warframe (such as Rhino ), or a mobile Warframe (such as Ash) to minimize any sort of risk in such a case.
Rhino synergises exceptionally well with Ignis, as he has abilities to quickly decrease distance to enemy, absorb damage when fighting at close range, amplify damage output and dispatch large crowds of enemies at once, and easily finish any survivors.
Due to a bug (6/25/13), with Volt's Electric Shield the Ignis can gain infinite range, turning it into a massively effective weapon. As of Update 10.8.0 the Ignis does not benefit from the infinite range bug. It may, however, still gain pinpoint accuracy.
It would seem that Ignis can "Headshot" enemies, dealing more damage. Based on this, it is assumed that weak-spots can also be targeted.
Due to its nature of AoE, this weapon is particularly effective against destructible projectiles.
Adding Heavy Caliber as another type of 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.
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.
Comments made by DE in Livestream 12 state that the Ignis would be getting a buff. This caused changes in the way damage is dealt, and allowed for multiple enemies to be hit in a cone of fire.
Increasing the fire rate with Speed Trigger has no effect on this weapon.
When using Shade, holding down the fire button when enemies are nearby will still allow shade to cloak you, letting you potentially deal high amounts of damage without the enemy retaliating.
As of update 10.3, the flame can be colored to the energy color.
Deals Fire damage, which can create combination elements when combined with other elemental mods, such as Ice. However, it will no longer deal the original fire damage, losing it's high bonus versus Flesh (+75%) and Infested (+50%). None of the combined Elementals as a result of using a heat mod surpass the effects of heat damage, so it is advised to keep heat as a standalone elemental. Note that the ignis has a very low chance of dealing procs and should not be relied on.
This weapon's range and duration of fire parallel those of the M9-7, the M9A1-7, and later models of the M2A1-7.
The volume of fuel the Ignis carries is physically impossible, in Reality, as the duration of continuous fire of the entire clip lasts far longer than actual flamethrowers.
This implies that the fuel contained in the small container is made of a futuristic material and not based on conventional flamethrowers.
Volt's electric shield can make Ignis flames hitscan. This however remove the AoE portion. (Possibly intended?)
Occasionally, the Ignis can force down its animation to idle while firing the weapon, causing its flames to shoot at the wrong direction compared to the pointed crosshairs. This does not affect the damage being delivered by the Ignis through the crosshairs, on the other hand.
Shade's cloak will stop weapon reloading sounds from completing or starting at all, and when coming out of cloak the ignis will play or finish the reloading sounds.
Occasionally while under Shade's cloak and firing the ignis, damage numbers will not appear on the enemy.
Since update 11.3 , the default fire color of the Ignis cannot be changed.
