Understand Heavy Caliber
Useful when…
- Rifle setups that can tolerate the accuracy penalty in exchange for the damage bonus.
- Players evaluating a standard-slot damage mod with a substantial negative stat.
What are the effects?
Heavy Caliber is a standard rifle mod with Madurai polarity. At rank 0 it gives +15% Damage and -5% Accuracy; rank 5 gives +90% Damage and -30% Accuracy; rank 10 gives +165% Damage and -55% Accuracy. Both effects grow with rank, so ranking increases the damage bonus and the accuracy penalty together.
How should I approach ranking?
It reaches rank 10, and the listed costs rise sharply: ranks 0 to 1 cost 30 Endo and 1,449 credits, ranks 5 to 6 cost 960 Endo and 46,368 credits, and ranks 9 to 10 cost 15,360 Endo and 741,888 credits. The increasing investment also buys a larger accuracy penalty, so rank according to whether the paired effects suit the rifle you are using.
What are the listed alternatives?
Lucky Shot is a Conclave rifle mod that changes Projectile Speed and Accuracy. Twitch is a Conclave Exilus mod with temporary recoil and accuracy effects on equip. Aerial Ace is a standard Exilus mod that refreshes Double Jump on kills while airborne. These serve different purposes and do not provide Heavy Caliber's damage-and-accuracy tradeoff.
Limitations and tradeoffs
- The damage increase is paired with reduced accuracy at every listed rank.
- Late rank fusion costs are high, and the accuracy penalty also grows with rank.
Common mistakes to avoid
- Focusing on the damage bonus while overlooking the corresponding accuracy reduction.
- Investing heavily in ranks without accounting for the larger accuracy penalty at higher ranks.
