Tips

 * Hellfire and Wildfire applies fire elemental mod damage to the weapon.  They do not act like base damage mods.
 * Cryo Rounds can be supremely beneficial for the Ignis, as it can help prevent enemies from drawing outside of the weapon's effective range. It also gives the Ignis crowd controlling possibilities, allowing it to slow down large groups of enemies at once.
 * 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 ) to minimize any sort of risk in such a case.
 * 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.
 * It is not recommended to use Vital Sense and Point Strike since they have little effect.
 * Modding for Puncture is not necessary as the weapon will currently puncture up to its maximum range.
 * 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 and on the Ogris.
 * Although a poor choice against heavy units due to not ignoring armor, it can panic Infested Ancients occasionally, allowing you to burst fire them for a short time, then while they are panicking finish them off with a better weapon.

Trivia

 * Amusingly, one can attach Cryo Rounds to 'freeze' your enemies with fire. It can also add electric damage if the mod is attached.
 * Ignis is latin for 'Fire'.
 * It appears to be a modified Grakata.
 * Was first shown in developer Livestream 5.

Bugs

 * There is currently no fire rate cap on the weapon when fired in semi-auto form, so an autofire macro would allow players to effectively instantly dump the entire contents of their magazine into a single enemy.
 * Volt's electric shield can make Ignis flames hitscan. (Possibly intended?)
