Tips

 * 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.
 * Against infested, adding infected Clip is usefull, because gas is more powerfull against Infested than Heat
 * 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.
 * Using the Rifle Ammo Mutation mod can help regain lost ammo when needed, due to the weapons quick ammo consumption. Alternatively, bring Team Ammo Restore consumables.
 * 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.
 * Vital Sense and Point Strike can be used on the Ignis, as the "rate of fire" of the Ignis is locally high.
 * If both mods are maxed, the critical chance may have about 12.5%, but deals about 440% damage.
 * The AoE of the Ignis is treated as Punch Through due to the flames being considered as explosions.  Despite this, the flame will not punch through enviromental objects.
 * Therefore the flames are not effective when directly pointed against Shield Lancers.
 * Punch Through mods allows the actual flames to pass through walls.
 * Many walls and objects can be punch through however, observed when firing at a wall and seeing damage numbers.
 * Using the Firestorm mod allows the user to have a higher blast radius, up to +24% blast radius.
 * Firestorm can only be installed in this weapon, Ogris and Penta
 * 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.
 * When properly modded and maxed, the ignis can easily take out frames in mere seconds.

Trivia

 * Ignis is latin for 'Fire'.
 * It appears to be a modified Grakata.
 * Was first shown in developer Livestream 5.
 * 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.

Bugs

 * 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.
