In my personal experience, I have found that using the Heavy Caliber mod on the Ignis can be quite effective. The Ignis is already a powerful flamethrower-type weapon, but when you add the Heavy Caliber mod, it takes the damage output to another level.
The Heavy Caliber mod increases the damage of the weapon at the cost of accuracy. However, since the Ignis has a wide AoE (Area of Effect) attack, accuracy is not as crucial as it would be for other weapons. The flames from the Ignis tend to cover a large area, making it difficult for enemies to escape the damage radius.
With the Heavy Caliber mod equipped, the Ignis becomes even more devastating. The increased damage allows you to quickly dispatch groups of enemies, especially in tight corridors or confined spaces. The flames can reach enemies around corners and behind cover, making it a great weapon for crowd control.
One of the main benefits of using the Ignis with the Heavy Caliber mod is the increased range. The Ignis already has a decent range, but with the Heavy Caliber mod, it can reach up to 30 meters. This means you can take out enemies from a safe distance, reducing the risk of being overwhelmed.
I have also found that the Heavy Caliber mod can be particularly effective against armored enemies. The increased damage helps to penetrate their defenses and deal significant damage. This makes the Ignis a great choice for missions where you encounter heavily armored enemies, such as Grineer or Corpus units.
However, it’s worth noting that the Heavy Caliber mod does reduce the weapon’s accuracy. This can make it less effective against enemies at longer ranges or those that require precise aiming. So, it’s important to consider the mission type and enemy composition before deciding to use the Heavy Caliber mod on the Ignis.
I would say that the Heavy Caliber mod can be a great addition to the Ignis. It increases the damage output and range of the weapon, making it even more effective for crowd control and dealing with armored enemies. However, it’s important to consider the trade-off in accuracy and the specific mission requirements before equipping this mod.
